Shimming the Wastegate

I already have a hks 2.0 mm bead metal headgasket with ARP studs, so im good there. And I already ordered the manual boost controller.. Ill just be real carefull untill I get a gauge. Worst that can happen is ill hit fuel cut off, right? Oh and 91 octane is all that is available. Is there any way to get higher octane?

Also how do I go about tuning my car so that it doesnt run too lean or too rich? Am I going to have to worry about that or will my cars ECU take car of that on it's own? Im gonna get a air/fuel mixture gauge when I get my boost gauge to make sure I don't get the lean condition, but if it were to run lean how would I change that?? Bigger injectors and lexus AFM?
