Since you said yourself you are pretty newbie and don't know for sure how to load a ROM...before you do, read ALL the info you can at this site (and maybe others) but this one will have what you need. After reading, read some more.
Read about all the ROMS that looks interesting to you, read what people who are using them have to say about them, and read them over and over again.

Just make sure you have all the info possible before you take the plunge and flash to a non-stock ROM......
