OO m plan should be out in this december update if its following the schedule, so g plan will be on the following month if nothing get wrong.
For your stats points, if you think you are good in evading attacks, good in your aiming, you can even ignore hp and dump all 12 points into attack. If you do check up on oo skills, you will notice it get attack up boost in both skill, a total of 6 attack up if both skill kick in. So even if you go hp full defense, its attack also wont actually be bad.
So just scale according to your own play style.
