Actually, I don't think it's that tricky to "put a name" on that theme. You are correct; that is The Ring Theme. The reason the Ring Theme is played during the trip on the Great River is because it represents how all of this came to be as well as recalling how ancient this conflict is. Those pillars, being representations of two Men who fought against Sauron during first War of the Ring, harken back to an age when Men failed due to the power of the Ring. Playing the Ring Theme during the journey also brings the movie full circle, reminding the more observant viewers that there is a lot more to come that is related, in part, to the past that led them to where the Fellowship and the audience are.
As for the "Mordor Theme," it could also be called Sauron's Theme, which incidently the first two notes for the Theme sound remarkably similar to the first two notes of The Ring Theme.
As for The Nazghul, I think there's an actual name for their wicked Theme (my personal favorite, closely followed by Frodo's Theme, The Fellowship Theme, and The Ring Theme). It's called Chant of the Ringwraiths. I wish the actual lyrics (which change from playing to playing) somewhere....
