CB channels are near 27 MHz, which your shortwave receiver might be able to pick up; depends on the radio. The FRS/GMRS channels fall into two clusters, one around 462.5-462.8 MHz and the other around 467.5-467.8 MHz, which are a little off the bottom end of the UHF TV spectrum (one or two TV channels' worth). It might be possible to pick FRS/GMRS channels up on the audio output of an old, sufficiently crappy TV, but tuning would be extremely tricky.
As for the handheld CB radios, let me Google that for you.
Yeah, I'm a dick. A tiny fraction of the blame may be assigned to Great Lakes Brewing Company's Christmas Ale (which is awesome), but it's mostly because I'm a dick. In vino veritas penis, as it were.

If the unit and its attached antenna are inside a vehicle, under many conditions, you can literally shout out the window farther than the handheld CB will work. Their only really successful use is with rock crawlers/wheelers where the spotter will take the handheld CB a few hundred feet up the trail and talk to the driver via a mobile CB unit permanently installed in the truck.
Effectively, the problems with a handheld CB unit are that the antenna is 90% shorter than it should be and then you stuff it inside a faraday cage and expect it to work. You might be able to get useful performance with a handheld CB unit using an antenna external to the vehicle but at that point you've spent more than you would on a mobile radio and gotten lower performance.
Something like a Midland 1001Z, properly installed, is pretty much the minimum successful hardware for CB with any usefulness.

Are ARS systems self reliant? (i.e. will they work when the "system" goes down?).
They look pretty nice, and while I don't want to go the HAM route yet (don't have the funds)
I'm mainly looking for a relaible system for a real camping/bug-out scenario, where I may have to leave the base camp for several hours, either hunting, or scouting, and really just want a reliable system more than anything. I essentially want a reliable 2 (min) 5 (max) mile range solution, that isn't limited to avehicle/continuous power source.
I do like the idea of the CB though, if only for the channel 9 Emergency function, where I can contact government entities if needed (from what i read, a lot of police/911 dispatchers still monitor channel 9????)

Quite a bit, in fact, if you're only talking about handheld devices. Handheld CBs have inherently craptastic antennas -- 1/4 of a wavelength is the minimum for ideal performance, but that's about 9 feet for a CB. So they have to use drastically shortened antennas, which have very poor efficiency. A quarter wavelength for FRS/GMRS is about 6 inches, so the handheld-size antennas are much closer to the ideal length and therefore much more efficient. That boils down to the FRS/GMRS radios burning a lot less battery power for equivalent range. Those CBs generally take 8 or 10 AAs, which makes them kinda huge and clunky, and they'll burn through those batteries pretty quickly when you're talking. It's common to find GMRS radios that run on 2 AAs, with size and weight savings to match. Higher frequencies also penetrate buildings better, which matters if you're not in the woods.
The principal advantage of a handheld CB is interoperability with vehicle-based CBs. Other than that, you're probably better off using higher frequencies.

There's all kinds of very-day situations when this is nice. On of the most common that I use the house radio for is to monitor SKYWARN, which is the NOAA severe weather spotters' network. It's really handy to be hearing real information about where the storm is going and what it's doing. It's saved us from having hail damage to our cars several times.

That's the kind of stuff I was look for Will. Gonna go do some research on the different handheld HAMS. So I should be looking at 2m systems only? or 70cm, or both? (if they even come like that...all the ones I've looked at thus far are both). If I do get a 2M "base station" and a 2m handheld, is there anyway to make the 2m vehicel/base station portable, short of a generator? Let's say I had a deep cycle marine battery with xxxx mAh, i can wire it to the battery and use it in short bursts to talk to the person with handheld? I'll be looking for handhelds that run off common battery types as well, that will easily be charged with solar solutions, unless you know if some right off the bat?

I have a small old B&W with AV Jacks in the back that will be used for picking up UHF/VHF Trans, and will double as a portable security camera.

Something nobody has mentioned yet is your FR300 and your old Bw TV. Since the move to digital broadcasting you may find little or nothing to see or hear on either of those units. There are a few low power TV stations still on the air using analog but depending on where you are you may not have much of a chance of hearing them.

As Will said, we hams, especially those of us into emcomm (emergency communications), are BIG on portable power for our gear. As an example, in my truck right now I've enough power options (gas generator, inverter, solar, gel-cell batteries, etc.) that I can run just about everything in the truck for two weeks alone in the field, and indefinitely if I restrict myself to just a couple of radios and lower power levels. A couple of solar panels, a charge controller, and a good sized gel-cell battery (I have three 100aH batts in the truck) and your base rig is powered for almost forever. And, of course, you can recharge the HT from that same supply. Many HT's also have optional packs you can buy that take standard AA primary (disposable) cells.
Even if you're not ready to become a ham yourself right now, for whatever reason, I'd encourage you to find an amateur radio club in your area and attend a few of their meetings. Most club meetings are open to the public, and hams generally welcome newcomers with open arms. By attending a few meetings you'll make some friends that you can call on for advice and guidance right in your local area. (Hams call this "Elmering", and a ham who helps others, particularly newbies, is called an Elmer)

My primary uses will be for charging batteries, realistically, that I can run my smaller gear off of, so I'm really looking for low wattage with lots of amp-hours, so I can recharge my stuff FULLY at least 20-30 times.
