My experience has been that one tunes the O/S, then the RDBMS / database, then the SQL statement.  At the statement level, it's a popular idea to correct those events that contribute the longest wait time.

That said, there are far better sources than our volunteer comments, given so broad a question.  My High-Performance Tuning with STATSPACK book runs about 700 pages, for example.  You might search the EE knowledge base for AWR and find prior messages and advice given.  One example is: http://www.experts-exchange.com/Database/Oracle/Q_23379052.html

Finally, it's always a good idea to be familiar with Oracle's tutorials, QBEs, and white papers.  One of several overview sections may be found at http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/autostat.htm#PFGRF02601.
