Welcome!
1. The 3mm thickness is a very good thickness for the jet.
2. You can put a small chamfer at the end of the tapped thread for the o-ring to seat properly. It will achieve a good seal when the jet is tighten (not over tighten - figure tight).
3. Yes it would, put the jet between 9'clock to 3 o'clock.
The install looks good to me!
