So what are peoples thoughts about stock intake vs. a ITB/plenum setup on a turbo motor? At what point does the stock intake become the limiting factor? Does the turbo negate the positive impact of the ITB's?

The OEM E30 intake manifold starts to become a serious problem around 300whp. At this point fitting a plenum style intake such as the 666Fab unit (no longer in production) large gains can be made.
Typically ITB's are not designed with positive pressure in mind so you have problems with air leaks around the throttle shafts. Take care of this and ITB's can offer similar benefits on a turbo car to that of an NA car. Having said that in most cases a suitably sized plenum and single reasonably large throttle is all that's required.

I'm currently working on a guide to using megasquirt on an M42, based on my setup, with the goal of consolidating the info for others to use. It's not a priority because I have school, work and the work that needs to be done to my car, but it should be done by the end of the month.
If anyone wants to share info on their MS setups, I can try to incorporate it into my guide, giving people alternatives to how I did things or just showing what can be done.
