I address the first part of your question in another comment on this post [1] (disclaimer, I'm a D-Wave employee and only talk about our offerings). As for what types of problems: D-Wave's quantum computers (and adiabatic quantum computers in general) are best suited for optimization problems. Some examples are scheduling, graph coloring, and other NP-hard problems. AFAIK quantum computing, as a whole, is very far from breaking any kind of interesting crypto.
