1. after adding my google analytics tracking code into admin template manager.... picture(tracking1) on front end on bottom i will see white strip picture(tracking)
You need to "paste" the entire tracking code there. Not just the ID.
The entire JavaScript code by including the open and end tags: <s-cript......... </script
About the other issue:
It is related to settings. Check your virtuemart backend and make sure you have the correct pagination settings.
Try to leave the "pagination fields" blank under VM Backend > Configuration > Template
