#1 - no.. that's a router/hardware related issue.

#2 - Location updating has been a culprit of diminished battery life, as it is always polling for location. with Fresh 1.1, I believe he removed it so it didn't drain the battery. The other ROMs, I don't know. I'm running TTG right now, and it updates once in awhile. Not a big thing to me, but you can always check it manually.

#3 - that's a google problem. I've had it happen to me too

#4 - again.. signal strength/reception is hardware related

#5 - I believe some of the ROMs compress some of the data to increase browsing speeds, but don't quote me on that. If you are on EVDO it will be faster than 1x. Also try Dolphin Browser for faster page loading. Remember, this is a Phone, not a computer, so it won't load that fast.

#6 - SenseUI is fully functional in all ROMs unless it is an AOSP, then its plain vanilla. Everything is fully functional, unless stated (like in 1.6 and 2.1 ROMs) or it has been removed and stated.

Just root the phone, if you don't like it than go back to stock. by rooting you can play with different ROMs until you find one you like. As long as you don't flash a different radio, you can always go back.
