CSS Styling & FB Wall Post

Hi,
I have 2 questions.

1) I want to style the register/ login page. How can I do it? Once a new user clicks Login with Facebook, he is redirected to a page asking for credentials for login in or new sign up. I want to re-design this page. Where can I find the CSS? Can I use the RSForms to re-create this page?

2) Under the backend Configurations > Status/Wall, I've given custom message that should appear on the user's facebook wall after successful registration. This seems to be not working properly. Once user sign up using Facebook, it won't post anything on their wall. How to fix this?

Hi Alex,
Thanks for your reply. I will try them out. One more quick question. How can I replace the facebook button to a static button like the one you have on this site? Each time when the page loads, I see this button loads up pretty slowly. Also, can I place a button like "Connect account to Facebook" or something of that sort for users who didn't use JFBConnect to login/ signup? I know the SC Login does this. But I don't use that module.

Thanks for the reply Alex. I guess I will stick on to the SC login for now.
