Congratulations, that should sound great and be easy to use.
A couple of observations, unless you're going to use the MacBook for other RAM-hungry applications at the same time you shouldn't ever need more than 4Gb of RAM.
You should have a second 500 Gb hard drive to serve as a backup for your primary music storage drive. It doesn't need to be as quiet or fast as your primary and an AC-powered 3.5" USB drive of that size would be quite inexpensive.
A great thing to have with a setup like yours is an iTouch to use as a remote control for iTunes.
Good luck
