Precogs only reduce the effective deck size meaning if you use 2 precogs in a 32 card deck, it is essentially a 30 card deck at the cost of 2 time quanta. If you are going to run that last posted mod, I would recommend -2 precog.
On another note you are wondering how to speed things up, I would recommend the same thing Rember and furballdn are recommending use upped entropy pends and aether mark, it allows for much faster start over your current build. so -4 aether pends -3 QT and +6 Entropy pends
Lastly you seem to be very high on darkness quanta with both steal and vampire maybe switch one of them to a shield of some other element
