Unusual to see the chainset sold without the BB cups included. They're all much of a muchness IMO - I've got 105 cups on a MTB triple and probably vice versa. You'll probably also need a selection of BB spacers, 1mm and 1.5mm, also available from SJS.
You need the 8 notch one - the 6 is for Dura Ace and XTR Octalink.

You'll know if you need the spacers, because the assembly simply won't work without them (if they're needed - if you see what I mean!). Its usually when fitting a MTB chainset to a road frame. With that combination at worst you can end up with rather more spacer than is healthy, but the good news is that the bearings don't have to be fitted very tight (nothing like as tight as the cups on a traditional cup-an-cone BB), so stripping shouldn't be a concern.
Note, if fitting a Shimano TRIPLE chainset a spacer is needed on the non-drive side, but for a double or compact a spacer is not.Quite why only for the triple, and not the doubles, know not I, and please please ask not how I know thus...
