Tomcat doesn't know what MS NLB is.  Depending on how your application
works and what it does, this may or may not be a suitable solution. YMMV.

Tomcat 6.0 should work just as well.

>> 1. Do i need to install Apache on both machines?

Apache HTTPD?  No.
One reason for using HTTPD is to make it the load balancer.  So you
would need only one HTTPD in that case.

Read the Cluster documentation for information about what Tomcat offers:

 http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html

>> 3. Do i need to cluster Apache as well??

Not if you're not using it.
