Ukrainian textbooks? (was NY Times - "The Retreat of the Tongue of the Czars")

[Grover Furr, Fastmail]

Whether Russian is declining or not, Ukrainian is surely becoming more 
important.

There must be textbooks to teach Ukrainian to non-Ukrainian speakers.

What are the best such textbooks for English; French; German; Russian 
speakers?

I'd be especially interested in the last. A Ukrainian textbook aimed at 
speakers of Russian would inevitably concentrate on examples of 
linguistic interference in such closely related languages.
