Another good language resource is Wiktionary, the Wikimedia Foundation project with the incredibly ambitious goal to fully document every word from every language in every (currently used) language. The root category for Latin on English Wiktionary is here. It won't do any translating for you, and you have to understand what all the grammatical terms mean, but it has complete tables for a huge number of words. (A few are lacking tables entirely, but those are mostly particular forms of other words with a special meaning in a particular context. EDIT: To clarify with an example: "abscissa" doesn't have a proper table, because it's just a form of "abscissus" with a special meaning in mathematics.)
An interesting quirk of Wiktionary is that every language's use of a given word is added to a single page: the page for "in" has sections for 26 languages. (I think some of them should be lumped together: why do Old English, Old High German, Old Saxon, Pennsylvania German, and Interlingua need their own sections when the they all have the exact same, very short, entry?)
