@thegalacticemperor,
Hmmm. I've only had crab straight from watching it be boiled at the crabshack by the water.. or had it served in restaurants, the best time being when it was stirfried with, I think, curry spices, in a wok.
I'll be interested in the answers re steaming or baking already cooked crab - presumably the idea is just to heat it. They both sound easy, but perhaps the steaming leaves you with more moist crab? On the other hand, baking for 9 minutes at that temp shouldn't dry it out...
