Create members-only section of website with embedded audio players

I have a website, [login to view URL], that is currently open to the public. Beginning May 18th, I want all the pages on that domain to be members-only, so I need: * a log-in page that incorporates my course logo at the top of [login to view URL] and some of the information currently on [login to view URL] * a system to recognize, accept, or reject their logins, including the capability to email them their password if they've forgotten it * a system that will let people sign up for the program even after it begins on May 18th * a page where members who have logged in can either listen to large audio files I'll upload to my server (@ 30MB each) via embedded players on the page that will work on any browser or or download them to their computers * embedded on that page, links or buttons that will also let them download weekly pdfs * a payment page that will allow late arrivals to sign up like this: [login to view URL] (but using my paypal buttons) * possibly (depending on the price) would also like a forums page for members like this: [login to view URL]
