Yow! New York! You should have plenty of selection of Buddhist teachers there!
If you find yourself attracted to Dzogchen, you might want to find a Nyingma lama to learn from because Dzogchen is basically the most advanced teaching of the Nyingma school. Practioners of the Bön religion also practice Dzogchen and most modern Bön is essentially the same as Tibetan Buddhism. You might also find Tenzin Wangyal Rinpoche's books interesting.
Many Kagyu lamas also practice Dzogchen--especially the Drikung Kagyu.
I believe Lama Surya Das is in Boston, so you could probably go and see him in person every few months if you really wanted to.
Anyway, if you decide to learn from a traditional lama, the things you will most likely work on first are shinay, lojong, and the four thoughts which turn the mind to the Dharma. Also many lamas give teachings about Shantideva's classic book which you can read here:http://www.berzinarchives.com/web/x/pdf ... _locale=en
I'm excited for you. You have so many great new possibilities in your life now that you've discovered the Dharma.
