just messing with it a bit...it looks like one option is to pre-comp a wiggled layer, then use the posterize time effect on the precomp....
any other methods out there?

That is probably the easiest.
you could actually just add a posterizeTime expression before your wiggle — like so:
posterizeTime(12); // number in parentheses is the frame rate you want to wiggle at — lower number = more "stepped //
You can use the extended wiggle parameters like this to create the required jumps:
wiggle(2,200, 1, .5, time-time%.5)
just change the numeric value of the "time-time%.5" parameter
wiggle(2,200, 1, .5, time-time%.5) jump every 0.5 seconds
wiggle(2,200, 1, .5, time-time%1) jump every 1 second
wiggle(2,200, 1, .5, time-time%2) jump every 2 seconds
wiggle(2,200, 1, .5, time-time%.3) jump every 0.3 seconds
the first and the second parameters (2,200) determine the frequency and amplitude as usual.
I hope this will shorten up things for you
iExpressions also contains a "snapping Wiggle" which is like first applying a normal wiggle and then snapping it to a grid such that if effectively jumps from one grid line to the next one.
As any iExpression, it comes with an intuitive user interface:
iExpressions is a commercial extension for After Effects that I develop and that is available here:
