I like Angelicum Academy's book lists very well, esp how they break them up by grade (so that age-appropriate books can be found easily).
What program/curricula are you using right now? I plan to use All About Spelling, New American Cursive, and Right Start Math with my 6yo. I recently got rid of SWR (Spell to Write and Read); it was just too much of a drain on my time. We've also used Prima Latina, and we were planning to continue with Latina Christiana 1, but that may change now that I've found CLAA.
Another thing I really like about CLAA so far is that the owner really encourages praying the Liturgy of the Hours. I've been wanting to do this for a while, and am planning to purchase the book Divine Office from Angelus Press this Friday (pay day ;) ). We'll see how it goes (or if I flop big time--haha).
