I cannot help you with the first point, but as far as performance analysis, I share with you what I've been using.

1) pgbench -- which comes with PostgreSQL
2) OSDB (
3) pg_autotune (
4) PQA (

You did not mention how your database is being used/going to be used. If its already in production, use PQA, but I personally have not implemented yet since seemed to be to take a performance hit of 15-25% when running it. Your mileage may vary.

I use pgbench for quick tests and OSDB for more disk thrash testing.

I am new to this; maybe someone else may be able to speak from more experience.
