You phrased the "coil tapping" part as a question, so I'm guessing that you want to know what it means...
Simple answer: a humbucker is basically two single coils run together in series. A coil tap (or coil split... same thing) shuts off one coil of the humbucker, essentially turning it into a single coil. It's a thinner sound than the pickup normally sounds like and is usually triggered with a push/pull pot or a mini-toggle.
On the other hand, if you weren't wondering what it means, just consider my answer to be a gratuitous, unwelcome sharing of knowledge from a guy who's more than twice your age (maybe even pushing 3 times), roll your eyes, and move on! :smack:
While we're on un-solicited advice... I read all your previous posts and those of our fellow members. I agree that you probably would have done better to work on your technique for a while, figure out what works best for you and the direction you want to go, and then start getting guitars. That being said, since you're obviously already going down this road, just make sure you make it worth it! Keep playing and keep loving to play!
