I built one of those for my buddy last year. They have changed a few things, last year they were green and had a carbon fork...cant tell if yours is carbon and painted or steel...his was black.
The components were great...the wheels sucked. We worked on them for a while to get them true enough to ride.
As far as the seat, you need to do a few things....one go on youtube and search for arts cyclery basic fit videos they have several of them and show pretty well how to set up your seat and bars. They are well done actually (even have decent component tuning videos if you want to do that)
Get that seat level, and rotate your upper body forward while rotating your hips back, and keep those sit bones on the seat, not other areas of your body. its a learned skill to get in that position, but once it clicks its easy.
from there if you want to rotate your seat down in front a degree or two, thats fine, but dont get too much down, as your just going to throw yourself forward on the bars.
I ride mine about one degree down or level these days. Also if your mainly street, change those tires that came on it...and hope your not in a hilly area, seems his came with a 25 rear cassette and a cross crank...sucks for major climbs.
