setup_finalize is the 'approved' hook to run stuff after all the plugins 
and components are setup, but before requests start. You need to be a 
plugin to do this obviously, and I'd recommend looking at other ways of 
doing what you want if possible, its not often you actually need to be a 
plugin.

2nd, is there a way to make Cat NOT load a model that's in

Right, so this is in:
http://cpansearch.perl.org/src/JLMARTIN/Catalyst-Authentication-Credential-Authen-Simple-0.03/lib/Catalyst/Authentication/Credential/Authen/Simple.pm

You have $app right there, and it could just be passed:

https://rt.cpan.org/Ticket/Display.html?id=44778

Has no tests currently, but I'm sure you can fix that, right? :)

With that patch, unfortunately the requirement will be that you setup 
__PACKAGE__->log( My::New::Logger ) (if you need to) before the call to 
setup.

Pull your model out into an external module, then use 
Catalyst::Model::Adaptor to load it.

You can then load a different module (which is blank and contains no 
functionality) instead, from config.

But to answer your actual question, no - catalyst will load everything 
in your application namespace, there is no way to be flexible.
