SPX Expiration

Its been a while since I have traded the SPX. I need some clarifications on SPX traded at the CBOE.

I know SPX stops trading on the Thursday before expiration, but does that apply to quarterly months as well?

Also I know that it settles to the Friday AM print, and the Merc options settle to the Friday PM print.

Just need some clarity on quarterlies! Thanks.
