This is a great link:

If you don't want to click on the link then the two fastest were
1. Willy Taveras- Astros (3.56 seconds from home to first)
2. Nook Logan- Tigers (3.74 seconds from home to first)
Also listed were Joey Gathright of the Rays, and Jose Reyes of the Mets. Reyes runs a consistent 4 seconds from home to 1st and Gathright a 3.78.
Ichiro wasn't listed, but I think he definitely should be, that guy has wheels. (Maybe it's because he's not as fast as he was in his younger years).
Ps- Carl Crawford was third in the AL.
