1) If you're using the {JFBCLogin} tag, to hide the button when logged in, simply change it to {JFBCLogin logout=false}. However, there's no current way (without adding some PHP code) to add the avatar image or welcome text like the JFBCLogin module. If you want to know how to do that, we can gladly help, but it won't be easy on a per-article basis.
2) There's a few ways to do this. Generally, what we recommend when someone asks this regardless of registration component is:
* Create a new article "Register for this site"
* Put some text in there about why to register or how to use Facebook to register along with the {JFBCLogin} text to add the button.
* Get a redirection extension, or add a rule to your .htaccess file, to redirect from Kunena's registration form to this article above
The alternative is to create a template override for Kunena's registration page and take out their form and do, roughly, what I mentioned above (add text, add the button, etc). For more information on template overrides, see:

3) I'm actually not sure what background and border your talking about. There really shouldn't be one built-in to the Like button, from JFBConnect at least. The module actually generates the {JFBCLike} tag, so it's the same mechanism for both. Is it possible you have a div around the Like button that's adding a background or border? If not, you can see all the options for the Like tag in the below config guide page. colorscheme is likely the parameter to mess with, but there's only 2 settings from Facebook available: light and dark.

If we're missing something, please send a link to the page the button is on, and we'll gladly help you remove any extra stuff around the Like button that we can.
Thanks for the kudos on the component, and glad you're liking it!
