I actually came upon a program that claims to be able to connect a 360 controller via bluetooth however I have my suspicions about it and won't bother saying what it was - maybe I'll check it out and make sure it's safe first.
With the triggers on the pad I just used Xpadder and mapped them to a couple of keyboard keys and in turn mapped those keyboard strokes in a few emulators most notably epsxe which seemed the easiest way at the time to clear up any headaches. Of course doing this in pcsx2 will preclude the chance of using the analog function of the triggers but I don't even remember if that matters with many ps2 games - or even if they had analog shoulder buttons on the official controllers anyways
