<LOL> So little time?? You're too funny!
General answers to your questions would be that shore diving in Maui is very good. There are some very good spots all up and down the West coast where you can rent tanks and shore dive to you heart's content. Maui Dive Shop publishes a free dive magazine (which they will send you before if you want), which has all the shore diving information in it.
Probably the best dive ops on Maui are B&B, Mike Severns, and Ed Robinsons. That seems to be the opinion of most people who have experienced Maui diving. They all depart out of the Kehei area.
If you want a guide for shore diving, Shakka Doug is the go-to guy. He is on this board and I'm sure will share.
Many will tell you that if you've never dove Maui, you should put Molokini on your "must dive" list. Some say that the backwall is the only part of Molokini worth diving, others really enjoy the crater. Having dove the crater, I definitely enjoyed the fishies, garden eels, whale songs, etc. We'll be diving the backwall for the first time next week, so I'll know more about that then. You also might want to dive Lanai. The cathedrals are reported to be a fabulous dive, and I know there are quite a few other sites on Lanai worth diving. Again, we're diving Lanai (2 charters) next week, so will have a full report then.
Tim, Al, can you help me here??
