Welcome to the forum! I think that you will find that about 99.9% of the things you would like to know about your new toy is right here. If you can't find it from searching, there is always someone here that has had the same problem as you and is willing to help you out. That being said....

First question. What problems are you having with the threaded messaging app. There are many different versions out there so you may have just tried to install the wrong one.

Second question... Any reason that you are wanting to replace your ROM so early in the game?
