For the bearing play adjustment bold, it must not be really tightened, it must be adjusted to have no play in the bearing.

For the two others, I don't know the torque value.

I didn't adjust the wheel stopper plug after switching from the factory mounted Marathon Racer to the Big Apple (what I did is removing one plastic washer between the fender and fork on the bolt at front of the fender to have more clearance between fender and tire). You just need to push the wheel harder to make it go over the wheel stopper plug.
