You can try AE Button to remap keys. There is alos a button config in Personal/Settings.

I had a Mogul too and the transition to the TP is pretty smooth...
I actually don't suggest you map too much to the buttons as they are much more easily pressed in your pocket than with the mogul.

TF3D2 (available in many custom roms now) makes the need for key mapping less important. Most of what you want to use is already available with the swipe of a finger and the program launcher tab is a much better way to go to quickly launch your often used programs.

I would give it a shot before you go remapping buttons.

As for the pictures question I do remember seeing a cab around here that will allow you to change the naming format but I'm not sure if it patches the save system or simply renames them after the fact.
