[OS X Emacs] How to call "call-process"

In Aquamacs 2-preview6, I have some minor problems executing an external program. The problems are not Aquamacs issues, they come from my lack of understanding of Emacs Lisp.
I have a program named PetesLookup that looks up words in a dictionary (it's more than that, but imagine it's a simple dictionary). The program takes one string argument on the command line and displays a Cocoa window containing the "definition" of the string. Then I click an "OK" button or hit RETURN to dismiss the window and terminate the program.
I want to execute the program from Aquamacs. I want to be able to highlight a word in an Aquamacs frame, hit a special key, and see a window pop up containing the definition of the word. I defined this in my startup file:
(define-key osx-key-mode-map (kbd "A-&") (call-process "/Users/siemsen/Applications/PetesLookup.app/Contents/MacOS/PetesLookup" nil nil nil "test"))
This almost works, but
Problem 1:
The PetesLookup program is executed every time I start Aquamacs. I obviously don't want it to execute when I start Aquamacs, but whenever I hit A-&.
Problem 2:
Unrelated to problem 1, instead of "test", I want to feed the program the currently highlighted string in the edit buffer. What is the syntax to pass in the string that I've highlighted with the mouse?
