The postgresql manual is good.
http://www.westnet.com/~gsmith/content/postgresql/pg-5minute.htm is a
five minute tuning overview.
http://www.powerpostgresql.com/PerfList/ is a good overview of basic
tuning, written for 8.0 but still pretty applicable.
Hang out on the pgsql-performance mailing list and see what other
people do - "How do I tune a database for X" comes up pretty
regularly, and gets good answers, so trolling through the mailing list
archive can give some very good advice.

Probably not. Mysql has a very different philosophy to postgresql. And
some approaches that are suggested to work around performance issue on
mysql may actually harm performance on other databases.
