New to flashing ROM

[blazinazn]

So everyone keeps recommending flashing a new ROM so I've been doing some research but I still have a few questions:

1) Is there a 6.5 ROM with TF3D2 that is basically a stock ROM with all the basic applications but with all the tweaks (i.e page pools etc)

2) I am currently using PIM backup to back up contacts and what not, can I restore my contacts with PIM?

3) I have custom landscape and slider icons, will those work with TF3D2?

Thanks!
