I don't know if there's anything that will do all three. You might take a look at Bordermania. It's free to try, but even after the 30-day trial period expires, parts of it continue to work. The freebie parts will do frames and mattes, though not as nice as Carolly's.

No signature, but that would be easy enough to do on your own. Do it once and save it, and then you can layer it over any image.
