Unhappy Problem with installing ROM. (newb)

Hey guys!
First sorry if this is wrong subforum, or there is an anserw for my problem. I spent about 5 hours on trying to do this.
Firstly I'm a noob in this subject.

I want to flash rom X - Gamer or True Smooth. ( are they any good?)
And I flashed generic .62 on my phone (Xperia Arc ) but I don't know what to do next.
I tried doing all those drivers, CWM, kernel things but I'm just lost now.
I can't learn all the things in one day..

Can someone give me links to best versions of things I need and say step by step how to do it? (or link to good toutorial)

Thank you so much for any help guys!
