Should one prune climbing roses the same as bush roses? Or should they be
pruned higher on the lattice to which they are tied?

Climbers bloom from vertical shoots. To increase the bloom, you want
the main branches to be horizontal. They will then produce more
vertical side shoots. The longer the horizontal main branches, the more
vertical side shoots.

See my http://www.rossde.com/garden/garden_rosepruning.html. This is
more about the philosophy and approach to pruning roses than it is about
the technique.
