E46 328Ci Brakes confusion

[shell320]

Hi guys wondered if anyone could help me. My rear disks are on their last legs and i believe my NSF to be slightly warped after a sticking caliper.
My question is what disks and pads to get?

I have been told that drilled and grooved are best but also that they are overkill. I have also been told that Green/redstuff pads are the best but again have been told red is overkill.
I am now completely confused does anyone have any suggestions/recommendations and an idea of the prices involved?

Also do you have to replace the pad sensors F + R when you do this and should i replace the other F caliper whilst im at it?

IME drilled discs are a definite
Do you track it? Forged holes or dimples if needed but I've had drilled discs crack on me more than once. Never got to the point of failure but I'll never trust them.

If you only use it on the road save your money (it is the rear brakes too...)
Just get some Textar stuff (OE spec) from GSF.
Stay away from cheap stuff on ebay. Utter rubbish.
