I'd play Eruption, the tapping looks really fancy and complicated to non guitar players. As for the stage tips, when you play the tapping part get your strap setup as if you woulds play behind your back ( strap looped over left shoulder and arm only, not over your body ) and toss your pick into the audience (optional) and hold your guitar out to the side as if observing it and tap away!
This is just a flashy move for the audience, it works for me, good luck!
