How does black stand in this ending?
Not particularly well I imagine Paul! We can't take on c4 because we lose the a-pawn and that's not a good idea.
I think, at the moment, that your suggestion of 22...a5 might be a very useful move.
It gets it 'off prise' for a lot of the variations, and covers the b4-square which is a handy square for white in a few lines.
If white responds with 23.Rhb1, then we can go 23...Be6. The variation you gave would be much more appealing for us in this case as we can take on c4 with the rook without losing the a-pawn. (In fact, he wouldn't have Kb1 at all in this line)
I can't get 22...d5 to work particularly well either; the Rb2 has killed off a lot of the fancy tactical lines which would otherwise work.
I'll keep looking at this though....my gut feeling is that we should still be fine : )
