Having just gone through this I might be able to help. Let me put on my nerd hat.
Short story
My experience is that Midland GRMS hand held radios work better than the programmable Baofeng (8W simplex mode) radios in urban areas. I've gotten about 1 mile in suburbia from GRMS hand held and from a 8W Baofeng. The cheap GMRS sounded better. In general no low power radio (hand held or mobile FRS/GMRS, Ham, CB) will work well a obstructed (hills, houses, trees) areas, they need line of sight to get the range stated. So the 32 mile radio, is on a boat in open water in the crow's nest talking to a mountain top on shore in clear weather, with 68% humidity, at dusk on the 5th Saturday in February. Using repeaters works very well and requires a requires a license as well as line of site to the tower.
Licensing
FRS and GMRS share frequencies. Provided the transmission power is less than channel's designated FRS power level and the equipment is certified for FRS/GMRS, it is considered FRS and you do not need a license.
The FCC changed the GMRS rules a few years ago. You can no longer buy a FRS/GMRS combo radios. They are only FRS and must operate at the correct power levels for each channel. Older radios are exempt.

All of the new inexpensive GMRS radios are really expanded FRS and do not require a license (see Midland, I'm not a lawyer)
The use of programmable radios as GMRS, presents a gray area with respect to transmitting. It is illegal but not really enforced (so I'm told - still not a lawyer). Receiving on a programmable radio is 100% OK, with exceptions.
Reality
Here is the part people mostly ignore; although, one might be licensed to transmit on a GMRS frequencies, you still are not allowed to use non-certified equipment that does not meet the FCC regulations (FCC part 95). I will let you read the government drivel if you want. I'm not condoning this but, my experience has been that for the most part people ignore this and do use programmable radios on GMRS frequencies. It's a hefty fine
if you get caught and they can catch you
if they want to. Besides the programmable doesn't sound any better. i.e spend $30.
Programmable radios (aka Ham radio) comply with FCC part 90. Your ham license allows you to build radios and GMRS does not. A Ham license gives you a fair amount of latitude here. However, a Ham license does not include GMRS frequencies.
There are GMRS mobile and base stations that allow more wattage and better antennas than a hand held. It does require a license ($70 for ten years no test); however, you need to have a similar set up on the other end for it to be effective. The use of GMRS repeaters also requires a GMRS license. FRS cannot use repeaters.
My suggestion
1. Spend $30 and get a Midland radio. They are inexpensive, work very well, and you don't need a license.
2. Go take your Ham test. It's pretty easy, no Morse code not expensive. . . until you start going on a radio binge.
You can study for the Ham exam on line for free. Just memorize the answers. Do this everyday for 1 hour, for a week and you should be good.
HamStudy.org: Technician class Ham Radio practice tests, ham radio flash cards, and ham radio question pool.
Take the test. I think it's a $15 test?
