Welcome to the board, and hopefully to brewing. Like everyone else has said, the 80$ kit will start you just fine. That's what I started with, and I'm sure many other s here as well have, and are currently still using it. You only need the basic stuff that comes with it to make great beer. The reason the rest of us have so much other crap, is because, well, it's just cool!
I got the basic kit, and a cheap 2.5 gal pot from the dollar store, and made some really good beer with it.
For right now, just stick to brewing what comes in the kits. Once you get a feel for everything, you can play with recipes, but it's best to first start with tried recipes, that way if something goes wrong, you know it your process, and cannot blame a bad recipe.
As far as your wheat goes, just brew a wheat kit, probably the simplest beer you will ever brew, and at bottling / kegging add some blueberry extract. That's how I make mine, although it's AG.
Have fun, and be prepared, your life is about to change!!
