Have players turn over their cards and have one main player controlling the hand reading. Typically this would be the dealer but if you rotate and the current dealer isn't that great go with a more experienced person. Having everyone talking at once, declaring their hands and everyone elses just adds to the confusion.

If you rule a hand out for both pots fold it so it's out of the way. Don't be afraid to push up the board cards, seperate, just a little the players cards to help identify the hand. Say, in Omaha 8 a player has A,A,2,8 and board is 2,3,5,J,4. Move his A,2 away from the A,8 and move up the 3,4,5 to identify this as possibly the best hi and lo. If another player has a 2,6 or an 6,7 then do the same for them. You might even need to decide them one at a time. Do it orderly too, work from player to player if you must, rather than jumping around. After a little bit it'll become easier and players will become better at calling their own hands.

Best advice is probably to make sure somebody trustworthy stays sober.
