If you look in the ZT thread a week ago you'll find a member and their less then acceptable cal done by BB. There is also more information about their calibrations in the thread for that topic. I am a SR member and wouldn't let them touch my display for free. You brought a great display and it should easily match/exceed your LCD for clarity and sharpness. If you could afford a ZT you should be able to afford a pro cal which I highly recommend. Well worth the cost and you will get 2 modes calibrated plus 3D vs. one with BB.
In the interim I suggest you try Sammie's settings - his ZT review on the home page was very informative and included detailed settings - should be easy to find using the forum's search function if it is no longer there. A number of your fellow owners have said using them improved their picture.
That being said using someone else's settings is less then optimal. Go pro, I just had my VT done last month and I am still smiling every time I turn it on and see that beautiful picture. DNice, Chad, Kevin Miller and a number of other very good calibrators do tours so it shouldn't be hard to line one up.
