I didnt have time to do the rears but went and drove it and I so far cannot tell that it is any better.
I am planning on sanding the rear tomorrow and if it doesnt resolve the issue or make it alot better I plan on order a BBK.

Heavy braking sessions with the same pads will only redistribute the pad deposits/transfer. It needs to be removed either by sanding or by more aggressive (track) pads.
The grooves are normal. Mine have them too. It appears to be related to the holes in the rotors. Whatever the cause, bedding in the pads will allow them to conform to the surface of the rotor and they will work fine.
You are on the right track. Sand them all and re-bed the brakes.
