I don't know offhand, I'm looking at newthread.php to see how that works, and I see that the "disable smilies" option is set in the construct_edit_toolbar() function (in includes/functions_editor.php). You could use hook location editor_toolbar_end in that function to create your option html (render a template, for instance), and preRegister it to the newthread and newreply templates. Or you could use the newthread_form_complete and newreply_form_complete hooks (which get called just before the templates are rendered), but you'd have to do the same thing for both hooks to cover all posting options (well, the ones from the "advanced" editor).

All that just gets the html to show up on the form. To process it, I'd probably use hooks newthread_post_start/newreply_post_start to get the values and put them in the $newpost[] array, then use hook newpost_process to do something with them (they'll be in $post[] at that point), and if you detect an error at that point you just have to put an error message in $errors[] to stop the post from being saved.

I know that's a really short explanation of something that's a bit complicated. If you know php I'd recommend searching for fetch_hook('hook_name') (using whatever hook name you're interested in) to see what's going on at that point in the code.

Also, does anyone know which array variable I can access to get post information (i.e. - post ID, post date, etc) and the user info (i.e. - user ID, user sign up date, etc)?

It depends on what hook location you're using. If you follow what I outlined above and use newpost_process to process your data, then everything about the post is in $post[]. The "current" (logged in) user's info is in $vbulletin->userinfo, but that could be different than the post if, say, an admin is editing someone else's post. I'm not sure if all the fields you mention are available. What I usually do if I'm wondering is I put in a print_r() to print the entire array into a file, then use it as a reference.
