Former Q owner having trouble with Pro

[daisyd681]

I just bought an Alltel Touch Pro. So far it is leaps and bounds above my original Q. I have searched on these questions but am a little confused on some things.
Firstly, I am trying to set up my Today screen to my liking. I downloaded the TF3D Config and installed a theme from freewareppc. It seemed to install (though it gave the usual "unknown publisher" warning). Are there specific themes for Touch Pro? Do I need to unlock my phone for unsigned programs? Also when I go into the native today editor and change things it doesn't stick. Everything goes back to default. I had Facade on my Q. I'd rather keep this phone as clean (not overflowing with apps) as possible. Where can I get themes that will work on the Pro?
Also I was under the impression that Live Search would work for the locate me feature. How do I make this work without paying extra to Alltel for it?
TIA for helping, and sorry if these questions have been done to death.
