Check out the Hebrew Vocab Lists page! I will be adding more and more vocab to the page, sorted by frequency.
Also, I plan on adding some vocab that is specific to individual books of the Bible. In other words, if you want to study an Old Testament book in depth then I'll provide a list of vocab that would be helpful for you to know when you approach the book. This will facilitate faster reading of the material with less time spent in the lexicon.
Don't forget about http://www.quisition.com/!
