I usually just: A) keep the hammock centered between trees, and B) keep the ridge line level - that handles 95% of any problem. Sleep well and enjoy your new Hennessy!
Actually, most folks will find that keeping their feet about 6" higher than their head helps to keep them from sliding down in the hammock once they've climbed in.
Other than that...I gotta agree. Hang your hammock, play around with how you set it up and how it feels for you, and learn what works best for you personally.
