Is there a link or recomendation on what tools work best for admin?

I am using pgadmin III, but find it is a bit slower then my app at returning
data, so I was curious for the purpose of tuning queries if there was a
better tool.

I did get my install done and am fairly happy.
I linked pg_xlog to /wal and base to /pgsql, using links it starts and stops
ok (did not have to edit init.d stuff).
