...I can either have a switch(like a regular tele/strat) or I can get a coil tap push/pull button...
I beg your pardon if I've misunderstood the question; But are you deciding between "EITHER" a selector switch "or" a coil-tap??
Your best 'likely' option is to have a standard 3-way (assuming you're going w/two pickups), and wire the humbucker for "series/parallel" switching (as oppesed to coil-tap).
You'll still get the great "single-coil" tone/attack from your humbucker when you want it, minus the awful noise produced when you coil-tap. Look for a humbucker w/4-conductor wiring. You can easily rig it to a push-pull pot on either the tone or volume.
