Tomcat 7 Production Tuning

We have a new application that will be deployed in production. We are using Tomcat 7. Is there a basics tuning parameters that needs to configured regardless of what kind of application we have.

For example can we increase maxThreads since by default its 200, set compression etc.

Also best practices to perform load test given we don't know how many users will be hitting the application. All we know max 4000 users but dont know if they all will hit the application same time during the day, or week.

You mention apache webserver. Is it somewhere in picture?
Load test is a bit tricky as it had to be created when making application, and very complex to make after.
Do you use tomcat native connector?

Its apache tomcat 7. We just http connector.

We will use jmeter to load test and also need to know best tomcat tuning practices. right now we have default tomcat settings.

You can have psi probe https://code.google.com/p/psi-probe/ installed to monitor tomcat thread usage
Probably you can compress all text/* as google pagespeed says. Cache hinting is not in tomcat and has to be done inside WAR by setting headers.
