Touch Pro Cleanup (Sprint Edition)

[ebuzz]

OK, so as a noob to phone tweaking I've posted questions in various threads to learn how to do these things and not brick the phone and have the ability to restore it to stock mode should I need to return the phone to Sprint or not like the tweaks or custom ROMs. Not sure I have gotten all the answers yet, but I'm still looking and trying to learn. I'm not sure of what First step I need to take. To install your cleanup, do I need to unlock the phone? To do any of the things listed in these threads do I need to unlock the phone?
If I install your cleanups, and the Sprint TV link is gone, does that mean I no longer have access to Sprint TV?
So many questions, so little time to read all these threads.
