i just used hi-temp napa paint, even on my brake calipers... its held up pretty well for over a year
as for powdercoating, make sure ya yank a bunch of shit off your car to get done at once, since they charge per batch, not per items.. so like 1 item would be the same price as like 4
i want to get some of this other paint that is like a fake anodized sorta look to do my PS reservoir and some other small things, but ive heard it isnt so great with heat, even the hi-temp stuff.
id get in there with some simple green, a rag and some water, go nuts cleaning by hand, then use some silicon based lubricants on the plastics, polish up anything else you think needs it. then hope to hell little critters like rats and mice dont come poop in your bay when its done
