“cookies” is a controller method. Call it in your controller and set
a variable for your view to use.

Also, given your example, I think you’re heading down the road to a
disaster. If you’re really storing a user id in a cookie, that’s
kind-of odd. If you’re actually trusting this value, that’s going to
be big trouble when a user decides to change the user id in his cookie
and send it to your server.

Yes. For one thing, the hard work has already been done for you.
There are also a number of 3rd party extensions / plugins for managing
authentication / authorization depending on the level of complexity
that you need.

If you haven’t already, you should most definitely read “Agile Web
Development With Rails” (2nd edition beta if you have a choice). The
book “Rails Recipes” has a good section on creating your own login /
role system from scratch (recipes 31 + 32).
