Answer 1

A nice, powerful, open-source imposition tool is included in the PoDoFo package: http://podofo.sourceforge.net/ It works for me. Some imposition plans can be found at: http://www.av8n.com/computer/prepress/ PoDoFo can do lots of other stuff, not just imposition.

Another useful imposition tool is Bookbinder (on the quantumelephant site). It has a GUI that appeals to non-experts. It is not as flexible or powerful as PoDoFo, but it can do imposition.

pdftk is more-or-less essential to have, but it will not do imposition.

pdfjam is useless to me, because there are a wide range of valid pdf files that it cannot handle.

I've never been able to get multivalent to work, either.
