Welcome to the NW Z4M Coupe Groupe.
Your first modification should be the driver and the second is remove the CDV.
If you're interested in doing HPDS events you can run with the Porsche or the Alfa Club as well as the local BMW Club. You can also do their low speed Car Control Clinic.
Send me an email at jsmillet at gmail.com and I'll send you a detailed tool list specific to your E86 Z4MC as well as a list of torque specs.
BTW the most informative forum is Bimmerfest; visit the Z4 FAQ page first.

The BMW CCA Puget Sound Region BB is also a good source for local information:
