You can use ghostscript (gs -sDEVICE=bbox) to get the bbox of the
non-white area. Leonard has explained the idea of "margins" in PDF.

If you intend to use a lot of of fonts (or want to include pdfs with
fonts), you should look at pdftex/luatex. We've spent years on getting
subsetting etc. right, especially with included pdfs.
