I would decide on how much you want to spend on this hobby ($$) and how much time you can put in. Both are important. Good advice to read the posts on this web site and try to learn as much as possible first. Ask tons of questions, and get a good book. Go to amazon.com and look at their selection of saltwater books, order one and read. I have one called Reef Secrets, by Nilsen and Fossa. Very good for beginners and advanced aquarists.
Welcome to the board!
And don't be afraid to order LR (live rock) from SWF.com - $109 will give you a good start on your setup.
