Thanks for the suggestions. I went ahead and booked myself a ticket, but am a little confused as to my seat reservation. For seat reservations, does DE Bahn assign me a specific seat, similar to what an airline would do? If so, how do I identify it? I see under my REservierung,

I have assigned Wg. [number], Pl. [number]

Does that refer to a seat? What does Wg and Pl stand for? I think I understand the rest of it, "Gang" means "aisle", "nichtraucher" no smoking, and Grossraum means, I assume, the coach, and not a compartment (correct me if I'm wrong).

Thanks again!
