I'm not interested in term Pharisees that is being used in an insulting way to describe legalism. After all, Christ said to follow their Teachings but not to do as they do, as in not walking the talk.
I am interested in the actual Priesthood and their role in Judaism and their Doctrines.
Pharisees did not dominate the priesthood. They were important primarily as rabbis--teachers of the Torah. After the destruction of the Temple, Pharisee rabbis continued to teach and practice the Torah, resulting in what we now know as the religion of Judaism.
Anything by Jacob Neusner is good on the origins of rabbinic Judaism.
For the basic beliefs and practices of Judaism today the two volumes "To Be a Jew" and "To Pray as a Jew" seem pretty good.
If you want an online resource, this website appears to be pretty reliable from what I can tell.
There's been a lot of scholarship in recent decades on the relationship between Christianity and Pharisee Judaism. E. P. Sanders is perhaps the single most significant scholar in this area.
