To be a moderator I assume you have to be active on the web-site for quite a while and make valid and useful comments on a regular basis.
As I am sure there are 1001 other people ahead of us to become moderators when the opportunity comes up I don't think it is something you should be worrying about right now.
As far as being a n00b, well post alot in this part of the forum. I have been on the forum for a while and I still manage to ask some pretty n00b questions so I guess there is a bit of n00b in us all at some stage.
