Vector to Raster Conversion

I posted this in the Acrobat forum a few weeks ago and received no feedback. I'm hoping that someone in this forum has come across these situations and can offer some advice

I produce technical manuals using FrameMaker 7.2. The vector images are primarily created with Illustrator CS2. I would like to be able to leave my native files in tact and rasterize the vector images when I distill the FrameMaker documents.

Also,

I am looking for a solution to batch rasterize vector images inside of a large library of multi-page pdf documents while leaving text and links untouched.

Can anyone suggest solutions for these two situations please?

Thanks,

Mark
