Sounds lik you done a good job! Probably nothing but air dry to get the toys completely dry. Beware of any toys that may keep water inside of it. Such a a squeeze toy/rubber ducky type toy. The water will turn stale and attract bacteria. Maybe toss them in the dryer if this is possible?
Any stuffies can be sterilized by throwing in the dryer, or wrapping in a garbage bag then into the freezer for a couple days.
The books, wipe down if hard cover, but paper books, I'm not too sure. What about putting outside in the sun for the afternoon in a bin maybe?
