Simple login/access & tracking for a page

Hi there,
Not really a support request as such – more like a little advice.
I know there are a lot of options out there for login access, but here is my scenario & I was just wondering if any of you may know a good solution that will work well for Enfold.
I have a page I’d like to restrict access to. The client wants to capture email addresses of the people that want access to this page (not for spamming, just resource tracking).
It’s a media gallery of resources, & they’d like to keep it as simple as possible, so perhaps a universal password (a simple password protected page).
I’m thinking as I type this, so perhaps a signup form on the password protected page with something like ‘enter your email to be sent a password to gain access’ or something like that.
I have Gravity Forms, so I guess I can set it up to automatically send out an email with that password easily enough, but how would I place that simple form on the password protected page – I guess that’s a template?
The final part of the equation is they’d like to track how many resources this user downloads – that’s where it gets trickier.
Any ideas around this part of the equation?
So login form capturing email address on password protected page.
Click tracking of that user when they access/download resources from that page.
Thanks for reading this far!
