Just done well over 100 very tricky, misbehaving decals on the Tornado, so I know exactly how you feel Aaron!
Do a bit at a time, setting yourself a reachable target at each session, and it's then not too bad.
I tend to start on one side of the model, for example the port fuselage, and mark off each decal on the instruction sheet as it's applied. The repeat on the starboard side, then the top, bottom, port wing, starboard wing and so on. This makes it more acceptable to sit and fiddle, maybe for a couple of hours at a time, rather than one extremely long and tedious job, and marking them off ensures you know where you're up to when you start the next session.
Good luck !
