Help! - Inadvertantly used non-paintable caulk!
I just replaced a bunch of trim pieces on the exterior of my home and inadvertantly caulked everything with non-paintable caulk including all the nails holes. I didn't realize it until I already started painting. Will it be ok as long as I put on several coats, or am I screwed? Removing the caulk at this point is not an option.

You might try scraping or otherwise mechanically removing the caulk, then applying the appropriate caulk. If paint won't adhere to the caulk, then a lot of paint won't adhere to the caulk.

I can probably easily remove the caulk around the window with a putty knife (right?) and replace it with paintable caulk. Perhaps I can sand the caulk off the face of the boards or maybe apply paintable caulk over top then repaint? How about applying a thin coat of wood putty over the caulk then repainting?

Try some Zinsser Cover Stain, I have had it stick well to silicone caulk but that was on interior. I'm not sure how well it would hold up outside.

I will likely remove the caulk around the window and replace with latex, but the caulk spread over the nail holes is actually not that noticeable. I think another coat of paint will cover those up nicely. I'm just concerned that the paint will begin to chip in those areas. Is that a possibility?

I'd try to rough those areas up with sandpaper. Paint doesn't adhere well to silicone caulk which is evidenced by the way it 'crawls' when it's painted. It would be best to coat those areas with a pigmented shellac like zinnser's BIN and then paint them.

Have you tried scrubbing off the residue with a thinner rag?
Zinnser's BIN is a pigmented shellac primer which is good at adhering to problem surfaces. BIN should adhere well to the silicone but on heavy silicone, if the silicone moves/stretches - the paint will crack.... so it's always best to remove as much of the silicone caulk as you can!

A thinner rag is a rag wet with paint thinner.
Have you tried cutting out the silicone caulk with an utility knife? It would probably be best to prime the remaining caulk with BIN. If it needs more caulk, caulk it after the primer dries. I'd be leary that latex caulk applied over silicone might not stay adhered.
