hmmm...
no matter what you do, ensure you do get some shots of just the two of htem, since the bride might have different ideas to the groom... and the mothers certainly will

But some ideas for involved the bridal party...
- shots of all the groomsmen with groom
- all bridesmaids with bride
- individual shots of everyone
- shots of each gm with groom, and bm with bride
- the more formal group shots
- the less formal group shot (mixing them up a bit)
- bridal party with B&G in foreground
- pair them up and get them to practise the waltz
But definately ensure you just take control and do the couple only shots (or at least with the bridal party in the background), because those are the ones they (or their relatives) will complain if they are absent.
Are you having an assistant along? Can they focus more on the B&G from a different angle whilst you do more group shots? And/or of course you can just zoom into them whilst doing the bigger shots
