I did a detailed review of all the things you are asking, here is the link:
LG Revolution vs Charge vs Incredible 2 - Android Forums
I took the LG Revo to Seattle today to test out 4G LTE, compared to the Droid Charge.
Summary:
GPS Very Good (Did knock out 5% battery life/1 hr, 45 m drive W/ charger)
5MP Camera OK
Battery Life went from 95% to 35% in 4 hours, check out my screen shots to correlate what I am saying.
