You would need to have your IT person set it up so when a page opens it opens to a new window rather than taking people off your site.

As far as finding out the page ranking here is a site you can go to and input the URL to find out the ranking. http://www.prchecker.info/check_page_rank.php

When you link sites you want to not only make sure there is a good ranking, you would benefit from finding sites that have good content that is a compliment to your genre.

Caution! Stay away from what is called a linking farm. It sounds like the offer for you to purchase is just that - a linking farm. It will do you more harm than good.

Better to put the work into putting on quality links. It will pay off in the long run.

Regarding a lot to learn, it is a never ending process. We have two choices on that (actually more, but here are two).
1. Get frustrated and stressed.
2. Learn to love the process
