The fact that it engages late is normal. Mine does it too. IT's a self-adjusting clutch, so there's nothing you can do except get used to it.

The chattering at idle is normal too. As per Terry HAines, the MTX-75 chatters a bit. IIRC, it's the throw-out bearing.

You'll get used to both of these after a while. Nothing is wrong.
