Yes you need to create a route for all controllers as I mentioned in my edit (if you choose to use routes).
For the 'login/signup' route problem...are you using links to access these URLs? If so, it should just point to 'yoursite.com/signup' and then your catchall route will pick it up and send it to the _remap() method, and since that method (signup) will exist it will send it there.
Edit: one note about this setup, if a user is named 'signup' you will run into problems...since you have a method with that name. Unlikely to happen, but still something to consider.
