Ah, we're obviously not dealing with a total programming-newbie here! :-)

Okay, so far so good. Just to be sure, I compared it with one of my
apps that uses username to log in, and the only other mention of
username I had was config.unlock_keys (which you might not be using at
all).

Actually, it does, just not placed in with your own controllers. In
its own directory, it has controllers and views and so on. Gems
provide Rails additional places to find such things. Some, such as
Devise, also let you install stuff into your app's code dirs so that
you can mess with them. (I'm guessing you did that with its views, in
order to make it ask for first and last name instead of email.) Some
don't, and are meant to run strictly out of their own dirs (modulo the
configuration initializer).

I'd agree.

That should be fine.

The rest of it looks good, confirming you're sending the right stuff
to the right place.

Yes, that's fairly important to understand. Another idea, though, is
to get a bit ahead of the curve, and use Rails 4 with its "strong
parameters". 4 was just released today, so it's now officially stable
so you can build with it confidently. Also, if you're trying to get
actual paid work in it, it's new enough that the competition will have
some struggles too, which evens the playing field a bit against
grizzled veterans like me. Oh, wait, never mind, stick with Rails 3,
better yet go check out Rails 2, pay no attention to the release no
longer behind the curtain.... ;-)

Ah, good progress.

Maybe there's still a validation looking for email in your User class?
Can you post that?

You could also go on a "search and destroy" mission: find all mentions
of email in your app and examine them to see if they could be the
cause. (Do you know about the "ack" utility?)

Come to think of it, there's a much simpler possibility; it may sound
stupid, but we've all done it. Maybe you didn't restart your Rails
server after modifying Devise. You need to do that to make it reread
the initializers, such as the one that tells Devise what fields to use
as keys.
