Extracting pages may be done with ghostscript. Actually, I never used 
this directly, but a very handy tool called GSview 
(http://www.cs.wisc.edu/~ghost/gsview/), which is a rather elaborate gui 
to ghostscript. I've been using it for years for different tasks, e. g. 
to write out pdf's from MS office programs at work (GSview is available 
for several platforms).
It is very easy to extract even non contiguous pages from a pdf document 
with GSview's convert function, which in this case doesn't really 
convert, but calls ghostscript's "pdfwrite" to write out the selected pages.
