Just ouf of curiosity -- can you show us the pictures? I have a feeling
it'll look awesome as a wallpaper..

Layer masks are what you need indeed. If I understand what you want
correctly, this is what you should do:

Add a layer mask to the top layer (right-click; add layer mask)

Click the layer mask preview (next to the layer preview) to make sure
it's selected. For some unholy reason the border that shows it's
selected is white here, but it's there.

Select the gradient tool, and proceed to make a black to white gradient.

Because the layer mask was selected, instead of a black/white gradient
you'll see the layer become transparent where the layer mask is black,
and translucent where it's gray. The white area will be opaque.

Once again, this is my interpretation of what you want to achieve. I
could be All Wrong.
