That's how i've done it so far, but i can tell you i was quite lost for the first few episodes. Just so many characters. But i think we've been introduced to most of the characters on the show at this point, so it shouldn't be too hard to follow season three.

Also, without getting too off topic, book 3 will be split into two separate seasons. And i do believe i read that the chronology of the book will be shifted around to make the show more sensible. So maybe you have the right idea.
