Make a new blank layer.

Make your selection on your original and copy it to the new layer and then blur.

I do not think your color cast will follow you to the new layer.

You still get the background contamination of the blur, even though you don't pick up the colors from the other layers. Gaussian averages a bunch of pixels and takes them from outside the selection as necessary.

Not if transparency is locked for that layer.

Consider the following images:

the layer contents are simply blurred as they are

the boundary of the layer content is selected and then the layer is blurred

the layer's transparency is locked and then the layer is blurred (but no selection is active)
