PPCGeeks - Verizon Touch Pro Customization

I just got my Touch Pro and I would like to do some of the things I've been reading about here. The problem is it is quite overwhelming! I don't want to go TOO crazy with changing a million things, I would just like it a little different. I know it is a way slower Version than other companies but verizon is really the best service in my area so I'm a little stuck. I also want to make sure none of this stuff is illegal, however, I don't think I care much about voiding my warranty with the big red.

1. I'd really like to have the flip clock and the weather status like I've seen in pictures, is this possible with the Verizon rom (I'm running the new one)?

2. Is it possible to upgrade to WM6.5? Do I have to pay for it or is it just an update like the new rom was?

3. What are some other things that I should really have? Maybe like the top 5 apps/mods/tweaks the verizon version needs.

4. Should I run TF3d? It looks cool but will it slow it down?

Thanks for any tips and opinions you provide.
