Looks like a great system, be sure to post pictures when you do get it.
I do have one thought here though. Have you considered getting the Studio 40s with a subwoofer instead? The Studio 40s have smaller less resonant cabinets and still get down pretty low. You could even stand not having a subwoofer for a while until you can afford to get the one you want. Don't underestimate bookshelf speakers, many folks prefer them to towers.
