I'll plunder my bookmarks for useful stuff...
A tree of Germanic languages... so you can keep the languages you need for the translation in order.
Time to put away your fancy dresses, this is what Tolkien said he imagined the clothes of Men in the 3rd Age to look like: the famous
Bayeux Tapestry.
I'm not sure whether the
Ardalambion has been mentioned yet in this thread... at any rate, it is good (and scholarly!) enough to be mentioned twice anyway.
Two sites I have linked to a couple of times already:
Old English Grammar (if you think you are capable of inventing your own Rohirrim names) and
Old English Pronunciation. Well, you won't need that urgently, but still.
Finally, probably my favourite non-Tolkien site:
Sacred Texts.
Of special interest for Tolkienophiles may be the resources on Christianity (Tolkien liked Augustine I think), the complete Anglo-Saxon corpus, Prose and Poetic Edda, the Norse Annals and lists of rulers, and the Kalevala.
