Thinking of upgrading to the Touch Pro, some questions for you guys using 'em

[BooDaddy]

Ok, I have had nothing but headaches with my XV6800. I am on Verizon and I am thinking about upgrading to the Touch Pro.

I had a few questions for you TP users.

1. Hows the GPS on the TP? does it stay active while the phone is in "standby" (when the display is off, but phone is on) Is it true aGPS on verizon? Are you able to use NMEA programs like google maps and Mobile XT with the GPS chip?
2. I am wanting to do some GeoCaching with this phone (which was my plans for my XV6800, but that didnt work). Are any of you guys using the phone for Geocaching?
3. Is it "laggy" on a stock rom?\
4. How much better is it than my XV6800? as in performance, GPS, and the like.
5. Are you happy with it?

Again, thanks in advance for any answers!
