Minor Kunena issues on new site

We have a new site at [login to view URL] There are 4 minor issues that we need fixed: 1) The Kunena Search Box is in the proper location but the Search Button is outside of the template 2) We'd like the word "Forum" replaced with the word "Database". I believe this would be called the Breadcrumbs in Kunena 3) Under "Create an Account" the Form is too wide. It looks unprofessional and should be about half the width it is now. The "Forgot Password" and "Forgot Username" also need fixed but it's probably the same code. 4) On the list of Categories there's a button to the right of the category selection that says "Com_Kunena_G0" instead of just "Go". That needs fixing.
