No, just for deciding new skills.  However, many of my skills/spells
take more than one skill-percentage-learned into account, so in a
way I guess it does...

Just practices.  I see too many ways to abuse the *using* scheme. 
Practices are
given at level, and optionally by immorts for good deeds, such as
a quest or whatever, so it is still possible.  Mobs can also teach
skills through their scripts, but this should be done minimally to avoid

I don't have the link on me now, but try looking for 'graphviz' on 
some search engines.  The actual page is burried somewhere at IBM, or
maybe Bell Labs.  The graphviz package contains 'dot', which I used to
generate the graph.  To put text in, you have to copy some TrueType
from your windows machine:  (In my example:  cp
/mnt/dosc/windows/fonts/* /usr/local/lib/fonts/ )

If you can't find it, let me know, I think I got the bookmark at work...
