Need registration and user-specific pages! URGENT!

I need a way to allow people to sign up – to register (become a member) on my site. I want to create the registration form with my own fields. After they register, they basically get their own profile page, where there is information relevant only to them (not viewable to other members). This information contains links to download files, etc… I also want them to be able to add content to their own page. This is a sports showcase site, so I want them to be able to upload their team roster(s), etc…

There are a few more features I want/need, but can anyone tell me if this is possible through existing WP plugins?? I really need to get this in place ASAP so any help is greatly appreciated!!!!
