what program are you using, photoshop?
http://www.planetrenders.net/renders/index.php here is a good site for renders, you can also google other sites... I myself just found out about this kind of thing haha I used to do it manually too.
And you'd have to have each layer outlined to the specific image you want from it so that it stacks well without having to lower transparency as you said. So render usage will the the best thing to do.
and what do you mean by borderless sigs? transparent ones?
You'd have to make some part of the sig transparent (easy in photoshop, I could explain if you want) and save it as a gif
for smudging.. are you usign a small tool or a big one? play with the size to have one that works for details... since you don't want to blur all the colors just add a smooth edge right..
