[Sting23ray]

Alrighty guys and gals....
i got my first BB about a month ago. In the excitement of the moment and due to my own curiosity, I downloaded every free and trial apps under the sun. I kept on installing/uninstalling and I now have an idea of what I want to keep.
I have noticed that my curve has become noticeably slow since I first got it so I am planning on doing a complete wipe (back to factory default settings) and then just install what I need.

Any pointers of what I will need to do after I wipe it clean? I have all my contacts on Google so I'm good there and I really don't care about the emails (on the server as well).

I'm planing on buying a couple of apps thru BB app world so I'm guessing they should still be there for re-download along with my licenses when I go there after the wipe?

Will I have to call sprint to re-push the Service books again?
Will they have to set the phone for voice again?

All pointers and tips will be appreciated....
