Avoid. Ectopic. Adept.
Ectopic forms are worse than normal constructs, especially once you have Boost Construct. Spending feats to make yourself worse is a bad idea.
Plus, you'll want to completely avoid the CPsi nerf. It's stupid and worthless.
Also, check out every way possible to improve your manifester level. Orange ioun stones, Overchannel/wild surge, arcanist's gloves (MIC) if your DM will let them count as boosting your ML, metamagic(/psionic) rods bound to your hands chakra, and so on.
