I'm surprised that Babylon 5 is so small! (And that Silmarillion is so big)
I've added the first three, but I think I'd prefer to stay away from Lord of the Rings entirely. I don't really know anything about the Silmarillion, but generally I don't chop fandoms into pieces anyway, and since there are even that many Silmaril fics out there, it's probably best that I keep that policy in this case.
