She doesn't have the Vale yet, but it was heavily weakened with Jon Arryn's death. However, she got the Three Sisters and she can take some castles until the Eyrie surrenders (I think the Eyrie is as impregnable as Casterly Rock).

By this point, she must have like 50,000 Black Knights + armies from The Reach + some of the Vale + Dorne.

So let's say she has 75,000 overall + a lot of supplies (which makes them stronger and healthier) + a few ships from the Iron Fleet (most were destroyed in the sack of Lannisport) + some things from The Citatel (like the Glass Candles).
