Yes, this is the recommended approach. The classes under WEB-INF/lib for each
web application are totally independent of each other, even if they have the
same names.

Actually, putting struts.jar on the classpath (or in $TOMCAT_HOME/libs) will
cause it not to work. The problem happens when Struts tries to create a new
application object like an ActionForm bean, and you've got the bean itself under
WEB-INF/classes or WEB-INF/lib. Because of the way that class loaders work, a
copy of Struts on the system class path will be unable to locate the
corresponding class, and you will get ClassNotFoundException errors.

There is a restriction in Tomcat 3.2 related to how you declare log files. In
Tomcat 4.0 this has been enhanced, letting you declare a separate destination
for the servlet log per application, instead of globally.
If you need to run under Tomcat 3.2, I suggest that you add some sort of
application identifier to the log messages being created. A common pattern that
I use creates log files like this:
[Application1] This event happened
[Application2] That other event happened
