One thing you might try doing is practicing chromatic runs on the fretboard with your right hand. When you improve try diatonic scales.

I picked up a great pattern which uses just the 1st and pinky fingers and allows scary turn of speed, I think I can hit inxs of 20notes/second with this one. It takes some learning but when you're used to it it's really easy. Apply the same pattern up and down the neck.

Have fun, bear in mind what usually is your picking hand is more coordinated and that flash as it all is tapping's a great way of cheating and making your life easier.
