Focus on your Tech Armor, Defender, Warp, and at least some points in Cryo Blast, Throw, and Overload saving the rest for your bonus power.
When upgrading the Tech Armor focus on the Assault Armor it provides greater protection and its detonation can wipeout entire crowds of Husks (which you'll appreciate during several missions) and knocks everyone down allowing you to get to safety/cover.
Also this goes without saying but I will emphasis anyway. ALWAYS have your Tech Armor on ALWAYS. Unlike the crappy Barriers and Fortifications your Tech Armor is not on a timer. It is active until it is destroyed so you can activate it and wait for it to recharge if you'd like before moving on. That way once it takes damage and explodes you can immediately use it again.
