First of all WELCOME!
I am new as well. I started by buying a 55 gal tank at an auction. I went to a used bookstore and bought a bunch of SW books (just to save a few $s). I just read quite a bit and asked the "fish lady" at the LFS (local fish store). They way I started was adding crushed coral, for my substrate. Added the water and salt, heater, PH (power head...moves the water)/canister filter, and checked the water stats without eh LFS. I actually waited about 2 weeks before adding any fish (I just wanted to make sure everything was correct..) I added the live rock first and the some starter fish. LFS told me some damsels are hardy starter fish. I got 2 yellow tail, 2 three stripped damsels and one blue devil damsel. I actually, waited for my first water change to make sure nothing happened. It was a pretty good change....except I didn't check the PH in my new water, and my blue devil got a little chewed on. Anyways, my point is, ask a ton of questions, and try to go with the majority. Take your time, find a good LFS, with people that know what they are talking about. Buy some used books, buy new books and read a lot on the web.
Good Luck!
