Hi bharani,
I hope I can shed some light on the first topic, interportlet communication. 
If the portlet is a java portlet, i. e. a class implementing 
org.apache.jetspeed.portal.portlet, then you have in the getContent(RunData 
rd) method the runData object. This contains everything you need, e. g. 
session, servletRequest (and therefore the parameters from forms submitted by 
the user) and servletResponse. So you can for example have a form in one 
portlet and displaying the result of some action like a database query in the 
other.
I don't know what it is like with other portlets (don't use them), but it 
should be similar in a JSP-Portlet. HTML portlets should be static anyway.
