1st website, need help!

For your issue with regards to Paypal and accepting payments, please read this page:

Basically Paypal does the work for you to create the payment page. You would just link to it. In a nutshell once a member pays you would add them to your other system to give them access to your website. Of course all of this could be automated using their IPN (instant payment notification) which scripts could handle, however, I would classify that as advanced work. You may find that hiring a web designer / programmer would be easier for you. However, if you can just do it manually that is something that you can probably achieve yourself if you take the time to read and learn some things.

To actually restrict your website so that members do not have access to other content there are more than one way to do this. You could either use some kind of members based script which you can find through Google, or if you are using an Apache webserver you could modify your .htaccess files to restrict certain directories from having access unless you have the correct username and password. I actually have a very old tutorial on this here:

With your other problem and removing the navigation, you would probably need to edit that page directly to remove that.
