I have a client server that is dedicated to being a Postgres 8.2.4 database server for many websites.  This server will contain approximately 15 databases each containing between 40-100 tables.  Each database will have approximately 7 web applications pulling data from it, but there will probably be no more than 50 simultaneous requests.  The majority of the tables will be very small tables around 1K in total size.  However, most of the queries will be going to the other 10-15 tables that are in each database that will contain postgis shapes.  These tables will range in size from 50 to 730K rows and each row will range in size from a 2K to 3MB.  The data will be truncated and reinserted as part of a nightly process but other than that, there won't be many writes during the day.  I am trying to tune this server to its maximum capacity.  I would appreciate any advice on any of the settings that I should look at.  I have not changed any of the settings before because I have never really needed to.  And even now, I have not experienced any bad performance, I am simply trying to turn the track before the train gets here.

Server Specification:

Windows 2003 Enterprise R2

Dual-Quad Core 2.33GHz

8GB RAM

263 GB HD (I am not 100% on drive speed, but I think it is 15K)

Thanks in advance,
