I think pulley bearings, any other thoughts?

Don't think; find out for sure! Just take your serpentine belt off *engine off of course* and spin the pulleys by hand. It will be quite obvious which ones spin freely and silently and which ones have play and make noise. Should take about 5-10 minutes.

But it is most likely your pulley from the sound of it.

_Brandon found a way to cheaply replace the bearings inside the pulley if you're on a budget: https://www.s2ki.com/s2000/topic/106...#entry23203421

I almost feel like there's 2 bad noises going on there at the same time.

You can also take the belt off and start the car to take all but the crank pulley out of the picture, but don't let it run very long that way (I THINK the max time is 1 minute but I did 15 seconds personally)
