Wow. Most of us don't get to go out and buy all those tools at once. First, the bandsaw. That's a really great one, and Grizzly is well known for quality bandsaws. 17" means you can resaw too. However, a bandsaw is not a perfectly intuitive tool. I recommend you start by buying a good book. I like this one:

If you have an itchy trigger finger, and just want to buy the saw now, that one is a good choice. I have a Grizzly 14" with a riser block that I got used for $250. If I'd had the funds, I would have much preferred a 17" 2HP model.
I don't know much about jointers. I use an antique jack plane for jointing.
For guitar building, a drum sander is probably the better tool. It's just more precise. I (and many others) built my own drum sander. I think the total cost was around $100, and it's 22". 12.5" really isn't enough to be a versatile tool. It's barely big enough for a strat, and many models are larger than that.
You'll also want a drill press, a good router, and a mess of hand tools, including some high quality neck shaping tools.
