NLTK doesn't provide any guidance about how to use a lexicalized grammar.

NLTK includes support for Combinatory Categorial Grammar (CCG), but
not for Tree Adjoining Grammar (TAG). The CCG package is only
minimally documented -- if you search our documentation index you get
to this page:
http://nltk.github.com/api/nltk.ccg.html

However, you would probably be better off looking at the C&C parser:
http://svn.ask.it.usyd.edu.au/trac/candc

I think that both the CCG and XTAG communities have their own mailing
lists, and so it would be best to post these questions there.
