Welcome to Boston Reefers!
That looks like a pretty good list to me. The guys at Skiptons and AquaAddicts are particularly helpful for setting up a new system, in my opinion.
Also feel free to post in the "reef talk" forum to gather advice and learn as much as possible about your planned setup before you take the plunge. That way you might avoid doing some things twice.
(Finally I think you accidentally posted in the forum of one of our sponsors, Fishy Business, in Chatham - another great store if you're down towards the cape. I'll see if we can get this thread switched into ReefTalk.)
