Octarine, sorry you've gotten a bit of a lacking response to this. I haven't had any experience with swaps myself, but from reading various threads and builds from the past 10 years or so, it looks like you have pretty much all you need. I would consider going with the bigger diff and maybe the 328 brakes at least in the front. The M44 diff will probably hold the power, but I would want the piece of mind of the bigger diff designed for the torque/power output, especially in the situations where you may need it. For the EWS, you may need to get it realigned, or reflashed for the swap as well. I guess read through the thread below, there's some guys on there asking questions about your swap situation:
