Pulleyblank's grammar is useful, but advanced. It is more relevant to Old Chinese rather than Classical Chinese.
The introductory work to begin with is A New Practical Primer of Literary Chinese
(Harvard East Asian Monographs). You can find this easily enough.
As far as Buddhist Chinese goes, see the following resource:http://www.buddhism-dict.net/ddb/
For Non-Buddhist terms see the following:http://www.buddhism-dict.net/dealt/
Once you go through the two above works, you can slowly go through Buddhist Chinese texts. You need to read Menicus and Confucius, and probably parts of the Five Classics, as they constitute the foundational grammatical patterns for Classical Chinese, and the main texts youth all read during their education throughout Imperial Chinese history.
