So if I understand correctly you have WMS layers in the map, with
corresponding layer nodes in a tree. When a layer node is selected (w/
a radio button) WMS GFI requests can be sent (on click I guess). And
you'd like that results of GFI requests be added to a (pre-configured)
store somehow bound to the WMS layer. Right?
I guess you could have each layer keep a reference to the corresponding store.
Also, why do you have a ProtocolProxy (with a WFS protocol) in your
store? If you use WMS GFI requests then you don't need that
ProtocolProxy.

Well I think you can forget about that, as I haden't understood you
when I wrote this. I thought you were looking at knowing where to
define your layer shemas, and I was telling you about the options you
had for that.
I hope I do understand you now.
