1) Go with two healers. More damage reduces the number of add phases, which can help your healers out a lot.
2) Your tanks and healers should, ideally, have a cooldown rotation worked out in advance to handle the spikes in damage. For tanks, the Tol Barad rep trinket is very nice on this fight.
3) Leave the rogue on the boss as long as you can. Your tank should be able to get all the interrupts on the add (for us, there are usually three per add). If necessary, send a mage or shaman to help out.
4) See what you can do to improve your fire mage's dps. 11k seems really low. You may also want to consider buying whatever BoEs you can for your hunter.
5) You don't mention it, but I am wondering how much shadow power you usually enter p2 with. For us, we found that p2 quickly became unhealable if shadow power was high at the start of p2. Conversely, if we enter p2 with very low shadow power it's almost always a kill. Minimizing damage taken during p1 is really important for this reason.
