Hi Anu_Dgr8

Answer:
1)Yes
2)session.abandon()
3)All viewstate data is stored on the client and is submitted back to the server when the user executes a postback.
viewstate stored in Hidden Field
4) You Having The Good Link Herehttp://www.semenoff.dk/en/Code-Corner/ASP.Net.AJAX/WebService-From-JavaScript.aspx
5)I think you are using the jquery plug-ins in the document ready function. But document ready will fire only once, not during partial postbacks. You need to call some functions after each partial post back is happend.

try initializing your jquery methods inside the below function

<script type="text/javascript">
Sys.Application.add_load(function() { . your initialization code.. });
</script>
