CiteGenie is a Firefox add-on that creates real Bluebook pinpoint citations from material you highlight in Westlaw. Normally, these kinds of features and applications aren't reliable, but CiteGenie received a good review here, so it may actually be worth trying.
(Of course, it should go without saying that if you never learn how to create citations, that will eventually be a problem for you.)
