1. Throw the bachelor party
2. Make a toast
3. I think there is something involved with the rings but I'm not sure what that might be.
4. I believe the best man and maid-of-honor sit up front and drive the bride-and-groom to the reception, if it is at a different locale. Groom then tries to sneak in some early action on the way over.
Basically, you take care of the details so the groom just has to stand up there and spit out I do.
Well, if you're going to actually give a real answer.
That last part is the most important thing. The best man's job is to make things as easy as possible for the groom.
Regarding the rings, the couple will decide how to handle that (which means the bride will decide). Depends on the type of ceremony.
Regarding the drive to the reception, it's a good thing to offer. I offered to do the driving for my friend and his new wife when they got married last year, but they decided that they wanted the time in the car alone. Not sure if there was any action involved or not.
Excellent points by Inky, too, especially regarding the bachelor party. Do NOT push the man to do anything he doesn't want to do just because you think he should. My buddy somehow ended up agreeing to a "no strippers" rule with his bride. We all teased him about it relentlessly, but we also made sure we did things his way.
Oh, and my speech did kick ass, in part because I got a lucky break. My buddy has a daughter, who was 11 at the time. I talked to her just before giving my speech and on a whim asked if I should tease her dad a little or a lot. Of course, she chose "a lot," giving me a perfect story to open with and get everybody laughing.
