How can I compress my portfolio into something that won't load like a bad animated GIF?

Can somebody please explain to me image compression, specifically with regard to creating smallish PDFs from Indesign files that contain large linked vector graphics?

No matter how many times I think I have a grip on compression and resolution and all of those terms, I still end up creating enormous files with no idea what is controlling what.
I am creating a portfolio in InDesign CS4 in which I have linked a lot of large files, mostly Photoshop files and a lot of very large Vector graphics (AI files). From InDesign, I will export the file as a PDF, using the High Quality preset for example. These files are huge, but are lovely when I print them. However, if I want to email a PDF to someone or create a smaller version, I have no idea how to compress these things.
If I try to optimize the PDF or export using settings as low as 72ppi, the file sizes are still huge and the vectors seem to load almost like animations. It seems the large vector drawings are the problem, but I can't seem to figure out how to "flatten" those without making the normal text in the file look terrible. The best option I have found so far is to just export the whole PDF as images, and then recombine into a new PDF but even these are pretty big and the regular text (captions, titles, etc) look a little gritty.
I guess I am not sure where in this process I should have been scaling down the large vector images or even the original PSD files (I was under the impression that these originals should stay uncompressed). Should I have scaled down the original images? Should I have changed some setting in InDesign? Is there a secret setting in Acrobat for vector images only that I can't find?
Please help me figure out what is controlling what, and help me avoid having to hire a courier to carry over a stack of flash drives instead of just emailing a nice, neat PDF.
