Andrea,
You can definitely use the Like and Send buttons to be for the Page. You'll need to add them manually with the JFBCLike and JFBCSend tags though, not using the Content plugin (assuming that's what you're using now).
To add manually each individually, simply add:
{JFBCLike url=http://apps.facebook.com/your-app}
or
{JFBCSend url=http://apps.facebook.com/your-app}
You can also add them together like the following:
{JFBCLike url=http://apps.facebook.com/your-app show_send_button=true}
Hope that helps, and when you get your App up, let us know. We'd love to see it, and eventually will be putting together a showcase of some sites/apps showing what's been done with JFBConnect.
Thanks,
Alex
