Just got Aegis, need help with what else to do to improve my character.

Just saved up for a week and bought my Aegis. Feeling really happy but I have no idea where else to put my money. Looking for advice on how I can optimise my passive tree as well as what I should look into improving next. Some initial ideas :

Getting a cluster jewel of some kind?

Changing gloves/ring/amulet to try and max Chaos Res

Flasks of some kind?

Spell Suppression?

Awakened/Divergent 21/20 skill gems

Getting rid of Ralakesh's impatience for rare boots with better res and max life

Getting +2 to auras Hand of the High Templar
