Since no one has chimed in.
I believe that complex gradients and transparency usage within vector will produce larger pdf output, so it may be benificial in this case to save some of those logo's to tiff from ai. Obviously that may rquire more time than you would like to budget.
Bear in mind, you may be able to leave them in ai format, but follow general layer usage guidlines. When exporting, if there is transparency flattening, all objects on the applicable layer can affected. Isolating text to a highest layer, and using multple layers will reduce the number off items being flattened. If you're working with only one layer, I would certanly expect to see an improvement.
Well thanks for the input but that's not really the issue. Very few if any of the items include any gradients and transparency isnt really an issue except on a handful of things that only appear a few times.
All of the images are placed as inline graphics on the table. Can I still split them out in seperate layers aside from the text? Ill give this a shot tomorrow although I'm not sure if it'll solve my problems, especially if I can't bust table info into seperate layers. Thanks though!
Any more ideas/suggestions?
Why is the file size important to you? Consider using a service like Dropbox or a private ftp server to get the large file to your client, or even just splitting up the resulting PDF into 2 or 3 pieces that are email-able.
You might pay close attention to your Illustrator saving settings. I would tend to expect EPS would be smallest of all the choices, and editable .ai with PDF compatibility would be the largest. Though your milage may vary a lot.
You could try Audit Space Usage in Acrobat Pro to see where the space is going...
The problem is the amount of EPS files.
This idea is a bit out there - but you can conver the EPS to raster on the fly with InDesign - which will result in a smaller PDF size. But you will lose the vector goodness of the logos - so be sure to quality check each of them.

David Blattner's idea is to have a transparent object (say just a square set to 0% transparency) then make a Flatterner Preset of High Quality, say 2400 ppi for vectors being rasterised.
This means that your vectors will be rasterised - but it will produce a smaller PDF size.
