I would say Sil-Glyde would be OK and smearing some on the piston boots wouldn't hurt. Even though I warned against using Permatex or CRC brake lube, I've also seen this and it's silicone based(not PAO/ester based like their regular brake lube) and I would think this is fine, YMMV - http://www.permatex.com/component/vi...formula-detail

So yes, lube the shims and pad backing plates.

Sil glyde is great, my preferred grease/lube for anything that touches brake fluid in late model toyotas (such as rebuilding calipers).

There's been many threads about this subject, I created one last year actually. The screws assist while installing the caliper, not for anything else. Once you have the wheel on and impacting 5 lugs to 100ft lbs that is what holds that rotor to the hub. Not sure how two weak little Philips screws would do anything more.

they also assist the centerbore in keeping the disks properly centered about the hub.

I ordered a tube of the red rubber grease Toyota specifies for rubber parts in brakes from the local dealer since my parent's Prius needs a quick brake check and I might as well pop out the slide pins and lube them. It wasn't too bad cost wise, $14 for a 3.5oz tube. I too had luck with Sil-Glyde(which is castor oil-based). I haven't tried pure silicone grease like Dow Corning 111(but Honda, Ford and GM call for that on their slide pins in most cases). I will say the green/purple Permatex, Bendix Cermalub and CRC brake lube is a no-no except for parts that won't touch rubber.
