Welcome to the ranks, you will definitely enjoy it!
If you're looking at midwestsupplies, I would start with this kit:

Gives you everything you need to brew a batch at a time. As you progress and get more adept, you may want to add additional carboys or a wort chiller as Drat suggests. But the kit above is basically what I started with 15 years ago--I've added to it substantially, but it still represents the core of my equipment.
Good luck, and feel free to hit us up if you have any questions--homebrewers love to push people down the sudsy slope!
