I'd get some pictures up if I weren't so damn lazy... but I just used some enamel paint and made sure to prep the surface really well before I sprayed my pillars. I wasn't too worried about ruining them since I picked up some extras at the junk yard for like 10 bucks. But they came out really nice.
Along the lines of what Sassy said though, I plan on wrapping my headliner, the B pillars, and then painting the rear pillars the same as the As. Think it'll look pretty good... But yeah, point being, wrapping is also a viable option if you don't want to deal with using the right paint / prepping properly.
