Twisted Steel is making a guide to using all of Link's options. If you want I'll ask if the projects can be a collaborated effort. It would help both forums.
I made some replay examples to help get started, tactics are listed in order of appearance in the videos:

Bomb down throw- press attack and down or 'C' (smash) down with a bomb, Link throws the bomb directly below him.
Bomb drop- (in the air) press Z/grab without a direction with a bomb, Link drops the bomb in front of him slowly.
Invincibomb- (in the air) press shield+attack together without a direction with a bomb, Link air dodges and drops the bomb behind him.
Instant bomb throw (0:12)-(in the air) Press attack+shield+any compass direction when near a previously thrown bomb, Link will instantly catch and throw the bomb in the direction you choose.
Bomb slide up throw,
I'm out of time I'll label these later.

Drop or throw a bomb in the air and catch it with Bair, Uair or Dair (not shown). You can use that aerial attack again without throwing the bomb until Link lands or is interrupted.
