checking to see if it's defined is simple:
<cfif isdefined("Application.#theVar#")>
or
<cfif structKeyExists(application,theVar)>

Well heck, I don't know what I did to make it work with Rays, but now in
trying it is not. Anyways, I got the <cfset> to work but how would I do the
isdefined.

Actually they both work.
Run this for proof:
------------------------------------
<cfset theVar = "foo">
<cflock scope="APPLICATION" type="EXCLUSIVE" timeout="5">
<cfset "application.#theVar#" = arrayNew(1)>
<cfset bar = evaluate("application." & theVar)>
<cfif isArray(bar)>
hooray!
</cfif>
</cflock>
<cfabort>

This unfortunately turned the array into a string. Ray's idea worked
flawlessly. Thanks anyways.

Well, since Application is a structure itself, you can easily do:
<cfset Application[dynamicName] = arrayNew(1)>
Don't forget your cflock of course.
