Forums about getting SQL Server 2000 Administration help?
This forum or ServerFault.

In the 13 years i've been working with SQL Server since 6.5 I've frequented several (SQL Server Central, SQL Server Performance etc) but it's hard to discern quality answers on these.

The reputation system on the Stack Exchange sites is a powerful tool to ensure higher quality answers as well weeding out the poor ones.

I can't understand your worries about upgrading: unless you have some code that (ab)uses sp_OA% or such you should be OK. The Upgrade Advisor will assist you here
