I've requested it from Adobe many times but unfortunately as of CS5.5 it is still not in the scripting API.

This script will go through all the comps in the project and turn the visibility off on any guide layers. for (var h=1; h <= app.project.numItems; h++) if (app.project.item(h) instanceof CompItem) for (var i=1; i <= app.project.item(h).numLayers; i++) if (app.project.item(h).layer(i).guideLayer) app...

You can just add an expression to the opacity channel for each layer you want to show and tie that to a slider in the parent comp. For example if the parent comp named "Main Comp" has an expression control slider on a control layer named "Control Null" then the expression on the ...
