  • Have a look at the Books link, Grant has a great free eBook on SQL server execution plans and how to read them and there's Tim Ford and Louis Davidson's book on performance tuning using DMV's. And even better they provide some scripts taht you can use out of the box to help you.

  • Unfortunately, there really isn't any sort of automated method for tuning queries. It's actually somewhat hard work requiring quite a bit of specialized knowledge. The two books down in the links in my signature are very good resources to get you started. If you have specific questions on a specific query, you can always post the query along with the execution plan here on SQL Server Central.
