You should also consider running a script which does a VACUUM VERBOSE weekly or twice monthly and emails you the last 8 lines of output. This will allow you to keep your FSM settings up to date.
Jim Nasby's article here: http://decibel.org/~decibel/pervasive/fsm.html has some good info about the Free Space Map if you're not familiar with it.
In addition, it's probably worth setting log_min_duration_statement to something like 500 or 1000 (500ms or 1s) so that you log slow queries. Note that 500ms is just an example, set it to a value you consider slow so that it will log your slow queries. Then, after you've gathered some data, run it through pgfouine. http://pgfouine.projects.postgresql.org/
