g1 to touch pro 2

[Firozu]

I currently have a g1 however i am thinking of going to the touch pro 2 but have many questions. I will start by asking:

i need a phone that can do video out and have google maps(the navi google maps which my g1 does have)

-does the tp2 have that?

also for messaging is there a way to change it so it is organized in conversations instead of single messages.
