As far as I know there isn't a co-op mod for the PC
You cannot play Co-op on Halo Combat Evolved or even Halo Custom Edition for the PC. A couple of years ago, there was a mod created that had co-op working however had many glitches and was not worked on enough. If someone knew what they were doing, it could be developed today however as of date, this doesn't exist, unfortunately.

Yes, Halo 3: ODST will feature offline cooperative Firefight mode.
