Shannon, the "Performance considerations" link from 
http://www-03.ibm.com/systems/i/software/websphere/express/indexexp61.html
or whatever version you choose from
http://www-03.ibm.com/systems/i/software/websphere/
may be helpful.
Note the performance advisor wizard in WAS v6.

InfoCenter topics include:
"Planning for performance
How well a Web site performs while receiving heavy user traffic is an 
essential factor in the overall success of an organization. This section 
provides online resources that you can consult to ensure that your site 
performs well under pressure.

Taking advantage of performance functions
This topic highlights a few main ways you can improve performance 
through a combination of product features and application development 
considerations.

Obtaining performance advice from the advisors
Tuning WebSphere Application Server is a critical part of getting the 
best performance from your Web site. But tuning WebSphere Application 
Server involves analyzing performance data and determining the optimal 
server configuration. This determination requires considerable knowledge 
about the various components in the application server and their 
performance characteristics. The performance advisors encapsulate this 
knowledge, analyze the performance data and provide configuration 
recommendations to improve the application server performance. 
Therefore, the performance advisors provide a starting point to the 
application server tuning process and help you without requiring that 
you become an expert.

Tuning the application serving environment
Start here for a summary of key performance tuning parameters. This 
topic describes how to tune various aspects of the application serving 
environment, such as the operating system, database connections, and 
application server Java virtual machine."

My only experience with these tools is on a lightly loaded demo 
system... it would be interesting to know if you find them useful!
