Kerlix - it's your friend
MRSA - NASTY stuff, had it 2x now - if confirmed, there are basically 2 choices - you get to spend a couple of weeks in the body and fender shop, taking Vacomycin (sp) or you get to take a 2 week course of Zyvox - either oral, or IV (again, a 2 week visit to the hospital)
I finished my last zyvox tonight, so the eating restrictions come off in 72 hours (there are interesting dietary restrictions when you are on zyvox, althought theey have recently losened then somewhat)
Did they say anything about "wet to dry" bandages? You soak a bandage in saline, ring it out, cover the wound, put a dry bandage over it, and let the inner bandage dry out (takes a few hours) - you then change the bandage - if it's stuck to the wound, it's OK to wet it with saline to get it off - in fact, you should) - this helps pull the bacteria out of the wound
There are all sorts of silver bearing bandages, but the MD has to prescribe them, and you may not be at that point
Good luck, heal well
