I might need a hand if any of you guys are available. I just need a free weekend first.

Seriously? An exhaust leak should not cause a misfire. That's a whole different matter. You are going to replace $100+ worth of gaskets to do that? Don't bother. I can't even begin to speculate what would cause a multiple cylinder misfire but it isn't your exhaust. If you burned up your cats, yeah, replace them. But the misfiring is up top somewhere. Electrical/ECU/timing... I'd groom it completely first and then see what gives. I would look on the intake side first.
