I don't think bitmap supports transparency... Ideally, I would use PNG
with alpha channel transparency. Promote the layer (it can't be
"Background layer"), select the area you want to remove, and then delete
it. Then, you would use the PNG Export wizard thing, and make sure the
transparency was in effect. However, I don't think that'll work for you.

To change the color of something... add a new layer, flood-fill it with
a color close to what you want the final object to be, then edit that
layer's properties... adjust the Blend mode and opacity settings, until
the color starts to look right. Now, go back and erase everything on
the layer, except the areas you want to re-color. It's the same
process that we use for digitally recoloring old photographs.

Good luck.

If you like, I could work up a sample from one of your images and send
you the .pspimage file so you could see how I did it. reply here or
contact me at the "working address" in my signature.
