Note that I am still using jurabib because it interacts very well with LyX. I can use the citation button (\cite) and thanks to jurabib's "citefull" feature I still get full citations in footnotes. Think of bibentry or similar feature with biblatex.
My previous question has been partially solved as I noted in my comments, so instead of editing it once again here's the (only) issue left:
How to prevent BibTeX or jurabib from adding a space before a colon or puncuation mark in both, bibliography and (full) citation text? I tried adding "language =" in the .bib file - both english and french are supported, says the jurabib guide - but it doesn't seem to help.
