If you bought all DA 7900, Nokon cables and a super high end Pinnarello frame and you don't know how to adjust a front derailleur, I'm guessing you had a shop build it for you (not meaning to sound negative).

I'd bring it back to the shop and have somebody do it (and show you how to fix it so you can do it in the future) for you lest your break anything expensive.

The cables probably just need to be tightened (new cables stretch a bit), which, to some degree can be accomplished by using the barrel adjusters, but may need to have the cable retention screw loosened, cable pulled tight, then re-adjusted.

Also, new cables in Nokon housing shouldn't need grease, maybe a very light oil, but they probably already had a teflon or related coating on them. A grease (usually referring to a heavier weight) may actually make the cable movement more sluggish.
