Root Help for Installing Custom Rom for Galaxy Tab

Hi guys! This is my first time on the android forums and would deeply appreciate if you help me.

So I have a Samsung Galaxy Tab P1000 (the 7-inch model) runs on Android 2.3.3 Gingerbread unrooted. I've noticed that it''s been slowing down and wanted to somewhat optimize it ang have it run on a later version of android.

I currently have no idea on how to Install a custom ROM, but I want to install Cyanogenmod 9.1 on it. I already downloaded the file from their website.

Other than how do I install the custom ROM, I have here more questions:

1. Will it make my device run slower?
2. Can I have a copy of the application settings so that when I finish installing cyanogenmod I still have my saved games and stuff?
3. Can I revert to Samsung's 2.3.3 in case I want to go back?
4. Is is it possible to have a copy of everything in it in case I want to go back?
5. What are the other things I should do before I install a custom ROM?

Thanks in advance!
