I almost feel like less is more in these spots. You had a great date, which is awesome, but let things develop slowly. Keep chatter to a minimum, set up the next date, and go from there. I know the natural reaction is that it feels good to keep chatting with her all the time, talking on the phone, etc., but I think it can kill some of the momentum and also put a lot of pressure on the next date.
Let her feel like she's chasing you a bit and vice versa. If she likes you as much as it seems, then she's not going anywhere unless something comes up that's out of your control (like getting back with an ex, met another guy right before you, etc.), in which case it wouldn't have mattered how you played it. I know the cliché is that the fun is in the chase, but I do think there's a lot of truth in it. That being said, I've been in your spot a couple times and usually react the same way.
In any case, good luck and hope it works out!
