Jens,
The setup process is the same for connecting your site to a Facebook Page whether you just want to read from it or if you want to read and post to it.
As for posting, the only way to post to the Page is by using the Social Toolbar, which is usually only visible to super admins. You can disable it entirely though, which would prevent even super admins from seeing it.
I hope that helps explain some, but if not, just let me know. We're actually working on an updated release of JFBConnect which will make the Channel creation process easier, as it's a few steps right now that we're hoping to streamline. Of course, if you run into issues, we'll be here to help.
Thanks,
Alex
