There's quite a bit to that... First, do you have a way to trigger them all? Second, do you intend to use modifiers (I think you should). You can mount them all in the same umbrella/softbox with something like the Lastolite Triflash Bracket. You can also mount them separately, with separate modifiers. You'll need light stands, too.

The best place to start is this set of posts by our resident strobism expert, Sean Setters: http://community.the-digital-picture...ead.php?t=1627. There are three sections, and although the links at the top are broken, the links to the next section at the botom of the first and second posts work.
