Matt, have a look at the annotated postgresql.conf for 7.x here:

http://www.varlena.com/varlena/GeneralBits/Tidbits/annotated_conf_e.html

If you have the default settings, you're likely hampering yourself quite a
bit. You probably care about shared_buffers, sort_mem,
vacuum_mem, max_fsm_pages, effective_cache_size

Also, you may want to read the PostgreSQL 8.0 Performance Checklist. Even
though it's for 8.0, it'll give you good ideas on what to change in 7.4. You
can find it here: http://www.powerpostgresql.com/PerfList/
