Brake Pad Recs + Min. Rotor Thickness?

Howdy, I’ve had a brake squeal for a couple hundred miles (I don’t think it’s the tsb since it doesn’t squeal in reverse). When I was rotating tires today, I noticed the rotors are pretty shiny, so maybe the pads are glazed? Looking for recs on pads since I think the rears are pretty close to replacement time, and I’d like to replace the front pads / resurface the rotors to maybe fix the squeal. Does anyone know the minimum rotor thickness on the third gens? Can’t seem to find it online.

For reference, my truck has 45k miles. Bought used at 34k, no clue if the pads or rotors had been replaced before, but I’d be impressed if they haven’t been based on everyone’s posts about these rotors warping and pads getting roaches quickly. I’m also running 35s on 17" methods.

 

The rotor's min thickness should be stamped on the rotor.
