No you don't need to, just put it on GFS.

Dito. No problem as general answer. But it sometimes depends on the 
application (what webapps you have).

You can put anything on GFS without problem when using tomcat. We have 
installed a 16 node cluster shared root, shared data, shared tomcat vars on 
GFS running without problems. There are some specialities but these are 
dependent on applications and stuff.

Hope that helps
