The "air" series is more expensive but your needs are...modest so you don't have to have the top one.
I like that config you listed also.
IDK if you want to add the wireless mouse or not.
Also, I'd opt for an SSD over a larger HDD if you don't think you will have to store a lot. They don't fail as fast. They have come down in price quite a bit. No moving parts.

but....I wouldn't get less than 128 GB these days. Depends on how much you want to store.
Make sure whatever you get is haswell processor, not the older one (older is on the 13 inch displays).
