Ok, So I read a bit about my droid and decided to root it via unrevoked. All went well because even though I am a newb, I read a few simple instructions. (ok they weren't that simple for me!) Now I read some more, and I decided to download my first ROM, and it is in the process right now. HOWEVER, All I used was ROM manager. I believe I backed up my "current rom" how my phone came. Anyways I keep reading about nandroid backup. Do I need nandroid backup if I just use the backup tool on ROM manager? Did I mess up big time or am I ok?
