How wide will you make the limbs? The few that I've done were around .260-.270 for 2" and 1.75" wides limbs, respectively. Your wedges should be 8.25". Your stack looks pretty good. That's what I've done before. I usually use just one .002 taper on mine.
The stack thickness depends on the form you're using. The thicknesses I just gave you is what Binghams lists for their forms, so if you're using a different one, your stack may be a little different.
