Member Area Navigation + Signup Form Colors

Site URL: https://www.changefitnesspt.com/

Hi! I need help with 2 problems I ran into dealing with member areas.

1. My client would like the member area navigation/header of the site to be the same layout as the regular website. Note: Not the same content, but we want the member area to have each link span across the header, right now in order to access different areas of the members site you have to hover over the "Change Members" link in the header, which then shows the rest of the pages to click on. We want it to be a similar style to the homepage where each link is spanned across the top of the header.

2. In the regular unpaid portion of the site, on the "online memberships" section, when you click "JOIN NOW" my client is requesting that the signup form for the member section colors be changed. She is requesting that the background be black, which then I suppose means we should be able to change the color of the other text + button/button text. 

I hope that clears everything up. Thank you for your help in advance!
