Wanted: Membership/Subscription Free Plug-In for PayPal

I’m considering using WP for a membership/subscription site. I’d like to know if there is a reliable and free plug-in that will allow me to sell memberships using paypal accounts and credit cards. I want it to work with the non-pro paypal account. It would be preferable if membership UN/PW and payment processing were automated.

Can someone let me know if this will be possible with WP or should I look for another cms?

Other features I will need are:
1. Forum
2. front-end file upload restricted to registered members
3. video embedding
4. automatically creation of a registered user “area” where each user can upload audio and video files

Is this asking too much of Word Press? I test drove Joomla and all their membership/subscription plugins cost money. Drupal has UberCart which is free, but Drupal is a pain to use and the administrator interface is not intuitive.
