Yes, it is Cromwell's story. This series (and the books so far) go up to Jane Seymour. I'm not sure when the final book will be released.
As to the series, I'm up to Henry's visit to Wolf Hall (instigated by Creumel as Anne calls him). If I have one major disagreement with the actors, it's with the man who plays Henry. He seems sort of wimpy to me.
