Hey Cal196,
I had one of those cheap radioshack amps for my Fett and I personally didn't like the sound that it produced. I would recommend looking into another set-up.
As for TK armor, I wouldn't use the radioshack amp either. I use the skullworx unit. This is by far, one of the best set-ups and I really enjoy it.
By the way Cal, your Fett looks great!
