(a first attempt to post seemed to go into a black hole ... try again ...)

The figured bass support in lilypond (wonderful!) is a little tricky to use
for three reasons:
1) The figures have to be entered in the reverse order (that is a six-four
chord is entered <4 6>). Of course, this assumes that you do call it 
that and
not a four-six chord, but I *think* is universally so.
2) The numbers are aligned from the bottom up. Again, I think the 
universal convention
is top down. You can work around this by inserting spaces (see my 
example at
http://homepage.virgin.net/richard.shann for how to do this).
3) The default font is larger than is normal for figured basses - it 
makes very good
sense for it to be a good size, but if you are used to the tiny size, it 
is very disconcerting!

The last problem is easily fixed:

\property FiguredBass.BassFigure \override #'font-relative-size = #-3

just before the figures does the trick.

The other two problems can be fixed via the following diff
