For the record, advice gets a lot better when you give us a quick overview of your overall battle plan. For all that some units are a little worse/better for the points than others, it's hard to judge a list if we don't know what your intentions for it are.
One suggestion I'd like to make: Your only Cryptek can't keep up with the Wraiths since you gave him the Chronometron, I think you'll likely want to keep him around the Warriors anyway. This suggests your Wraiths don't really want to stick around the rest of the army.
3+ Invul save or not, that makes them vulnerable and they're expensive. Fit them with the cheaper Particle Casters, and maybe switch that second Detachment to Novokh to improve their CC punch (also helps the Scarabs if you ever throw those at something).
Ask not the Eldar a question, for they will give you three answers; all of which are true and horrifying to know.
