It sounds like you have a lot of really great ideas already. I'm not sure how much more you actually need. Just a few smaller stocking stuffers, or things like books, clothes, pajamas will put more presents under the tree without breaking the budget.
I sell Discovery Toys and we have some really nice, fun, educational toys that will last forever. They all come with a lifetime warranty so you know you're getting a quality gift. Check them out at http://www.discoverytoyslink.com/karenchao and let me know if you want specific recommendations or more info (p.s. you can host a party and get your toys for FREE)
