It sounds encouraging!
One small word of advice: even the very best IEPs need tweaking as time goes on, especially in the first year or two. It's a normal part of the process-- because of course the whole point of a plan is progress, which necessarily means change. When that happens, don't feel discouraged, and don't feel like "well, I asked for this, and now I don't want it, they're going to be a pain". If something needs tweaking, or even outright changing, just let the appropriate people know, and let them know if you have questions or clarifications or suggestions (in writing/email, preferably). As long as everybody stays calm and polite, it won't be a big deal.
