I've no clue why it's so big, I've never had this before (unless CS3 just automaticlly makes files bigger by virtue of it being CS3).
It's an ad with photos (imported from P-shop), but like I said i'ts all flattened..weird. I'm in process of getting an ftp, but till then figured I'd find another way.
Your vector data in a pdf is very small unless there is a huge amount of control points on the curves. Which means that the large file size is coming from the pixel data. If the embedded image(s) is a tiff, convert it to a jpeg, and do a little bit of compression on it, also make sure the dpi is not more than 300 (you wont see the difference beyond that) and you can go lower. 150 dpi will still look decent when printed.
