David,
You'd be surprised how much tying material is purchased at hobby shops and sewing centers. I get a bunch of stuff in those places. Have you priced pheasant tail feathers at a craft store? Way cheap.
That fly looks buggy as all get out, as Eric said. You've already recieved great advice from the other guys on some improvememnts. It's kind of nice to keep the first fly, then after a monhth or two of tying look back at the first one. You'll see great improvement.
Congratulations on joining in on the addiction.
