I talks alternately about adding engines and defining the default programs of a document, thought the two things are not really related. Wll, they are in some way, but obviously engines have no influence on the default programs defined in a document.

TeXShop executes programs that are in /Library/TeX/texbin (which points to the active binaries of your TeX Distribution) by default. Engines (see below) execute programs that are along the PATH variable passed to the Engine or the path explictely given (e.g., /opt/local/bin/biber)

The Engines are really just shell scripts stored with the extension .engine, taking a single argument (the file to be typeset --- with extension) and is executed with Typeset->Typeset (Cmd-T) when you have the line

% !TEX TS-program = engine-name

where engine-name doesn't have the .engine extension (e.g., pdflatexmk). You can create an engine that calls pdflatex, biber, etc. on the file (you need to strip off the .tex from the file name). 

Let me know what processing you wish to do and I'll try to help out.

Good Luck,
