It's better to do Stat Training (i.e Ten Tom Gym/Ramis/Syri) first, then spend your level up points. Stat training has diminishing returns, level up points do not. You can still max your stats, but it will take longer.
If you're not Stat Training, you don't want to spread your Stat Points out too much. 13/Level is enough to keep two stats maxed and one stat high-ish.
As a Kineticist, you want Will maxed, unless you're a Bimbo/Bro (Instinctive Psifocus). Int is useful, but not as much as you'd think, since most powers can't miss.
Unless you took Third Eye Aim, then you want it maxed.
I suppose I should have asked for Abilities. Perks are pre-determined by Class and Level, so they don't tell us much.
