Hello Tim,
What a familiar problem.
We had a similar experience building an E sized geological map for Yemen.
This was a couple of years back, but what we did was to create an EPS file
as you have. We then imported the EPS into Corel Draw as an interpreted
Postscript. This creates vectors within Corel. Once the map is in Corel
you can modify the colors to CMYK in a number of different ways.
Another option is to send the EPS file to a commercial printer with a high
end RIP (raster image processor) Once the EPS is RIPed you can take the
resulting raster into something like Photo Shop and Manipulate the colour
model there.
I've have several years experience dealing with this problem and I can't say
that there is an easy solution, but we were able to work around the problem
and get very nice results.
Feel free to give me a call if you are really stuck.

Subject: MI, Help with exporting EPS for offset printing
