Welcome aboard. The best advice I can give is don't pick a pattern with curved pieces like I did for your first quilt. Also don't expect it to be perfect. Don't worry, your skills will improve as you go and most mistakes won't be noticeable after your first wash. At least that's what I tell myself. Just do the best you can, relax, and have fun with it. As mentioned before your local library is an excellent resource for information and ideas.
