You have made a rod for your back.

Ouch. If it had been known that you are using raster images and not
vector art most responses will have been different. Corel Draw images,
in my experience, include data that processors such as Ghostscript do
not like. These are proprietary postscript code that enables such
things as multiple pages within the eps file.
Now, I am going to assume your images are not in colour and that they
use an RGB colour space. First thing to do is to take them into an
image editing program such as Photoshop and convert the eps images to
greyscale. This will remove up to two thirds of the image payload. If
they are colour however, then leave them as is. Set your print
resolution at this this point too.
From Photoshop (or your favourite image processor) you can save them
as tiff image files but *do not* use LZW compression. Convert the
images to pdf from there. You are not looking at a large number of
files so it will not take long.

pdf compression is potentially better higher than most eps compression.

Herb has suggested an easy route or you can use Preview, or you can
open the files in a program, select File>Print and from the print
dialog select Save As PDF.

Unless you print the oversize pages on oversize paper and bind them
together when all are printed ;)

Probably has more to do with the eps images.
