Your web applications are on all of your SharePoint servers that run the web
application service. You don't have to move anything. Also, web applications
are not created on the WFE, they are created in Central Administration,
which I certainly hope is not running on your WFE.

So just to clarify, a web application is created in IIS and is 'replicated' by
SP to all other servers running IIS, which is all SP servers.
So what makes a WFE server a WFE server besides not pointing to it by URL?
In other works, if I create a web site call Test.net.ex
And I get to the website by type Test.net.ex in my browser, my IP for
Test.net.ex will point to all of my WFE servers, or be directed to it by network
load balancing or a front-end switch, but not my application serves.
So do I go into Central Admin \Services on Serves and turn off all of my
services except the Web Application service on my WFE servers? What about
Incoming E-Mail and Workflow Timer - I keep those started on my WFE.
Should I be turning those off on my App serves?
Is there a good white paper on proper configuration of WFE and App servers
available?

I don't know if this will work but you should create a backup of the farm to a
test environment and try it out there if you don't get a reliable answer. Do you
have a test farm you can break? I would try this there if possible.
