Depends. I use handlebars on the front, but mostly just to rest my hands
on them (http://dirkb.dnsalias.net/python.html) . I find them useful to
maneuver in very short turns (U turns on small roads) and I feel more
secure at high speeds. But it is said it is more difficult to learn to
cycle with them, as you have to learn to steer with your feet and not
with your hands, and the handlebars will slow down that process.

Put the pivot about at the border of the seat. It is not such a
sensitive thing, as long as you do not put the pivot totally behind or
in front of you. See the photos on this page:
http://www.python-lowracer.de/projects.html
they all have the pivot more or less at the same place place.
What you really determine when setting the pivot is the negative trail
(and IMO it should be as low as possible).
