Movies: From what I've read, LotR was indeed the last of a series of contractually obligated movies that were worked in with the TNT deal. It was also given the chance to serve as a pilot for a new series on SciFi. This is not to say that there won't be more--but we'll have to wait for any positive information on that.
The Hand: I think I read this from JMS, himself, but can't be positive. While I think it's more than likely that the Hand were the aliens from Thirdspace, there's nothing to say that they aren't indeed First Ones. The galaxy is a big place, and to presume that all the First Ones who had ever existed decided to vamoose with Lorien is a bit much. It's also possible that they were first ones who had explored beyond the rim, and simply came back around that time. A little convenient, but that's TV for you.
The Hand and Crusade: The Excalibur was focused on one mission--to find a cure for the Drakh plague. The Hand would not be their concern, at least not right away (and LotR happens 3 years after Crusade began). It is quite possible that the Excalibur
would have had a run-in or three with the Hand, but we'll never know until someone finishes Crusade or we get an official timeline for the series. With JMS, it's hard to say, but he's pulled the "bait and switch" routine before, and he HAS gone on record as saying that Crusade wasn't going to be about what we thought it would be about. Now, having said that, I think that the season finale scripts pointed the way in which the show would have originally headed, but that's just conjecture. Besides, who's to say that the Hand weren't part of the reason for screwing around with the Shadow-tech (besides the power-grabbing, and the millenia leap in technological development, that is)?
Then again, take these ramblings for what they're worth. And remember how much you paid for them.
