Looking for a simple user sign-in & method to track page views

I’m running a WordPress site for a client, and they want a section for whitepapers where the user fills out a form providing name, email, company, etc, and then is taken to an index of whitepapers that can be viewed online or downloaded as PDFs. We want to be able to track the user’s movements within that section of the site, so we have a record of which whitepaper pages the user visited.

So I need two features:
1. A very simple way for users to register/login, preferably by filling out a simple inline form. The tricky thing here is that I don’t want it to seem like they’re opening an account, just providing some information in order to gain access to the whitepaper section.
2. A way to get a report of which pages within the whitepaper section that user visited. Ideally this report would output to a spreadsheet of some kind, but an email alert (userX visited whitepapers 1, 3 and 5) would work too.

Any ideas on plugins and/or uses of built-in WordPress functionality that might get the job done?
