You can either leave the old server alone (cf. your point 4) or do a
pg_dump and then reload the data into 6.5. (Did 6.0 have a pg_dump?
That was way before my time...)

You should recompile, I think. The current server might still accept
connections from client libraries that old, but 6.0 is a long time and
a lot of bug fixes ago.

Sure, if you give them separate installation/database directories and
separate connection port addresses. Assuming you want to leave the
old one where it is, just make sure you specify non-default settings
for --with-pgport and --prefix while configuring the new code.
