I dont touch my chest on inclines anymore. Not only does it mess with my shoulders but my biceps are in the way anyway. I use a squatters pad on the bar when doing inclines, and I do them after my declines now to reduce strain on the delts. I also go pretty slow on this one so the weights are lower than would otherwise be used.
I am once again also having trouble with flats even if only doing one set, so I am dropping them except rare occasions (whatever that means).
Declines
Inclines
Carefull use of the pec dec (no crazy stretching anymore)
I do rotator stuff with 15 pound dumbells and I bench upper 300s, I would suggest 5 or 10 pound plates for most, SLOW, deliberate, and do not force yourself to use a painfull range of motion.
