Oh I enjoy a good system build, especially with a budget... it's fun!
Are you locked into the powered speakers? That might limit the number of devices you can hook up if they have varied interests.
I've been kicking around this same scenario for when my kids are a bit older and wanting their first "real" systems. If I was locked into new I think I'd start with a trip to Parts Express and get a pair of Dayton B652 or B652-Air. I have them as near field monitors at work and they are amazing for around $60 shipped. Parts Express also has some very inexpensive amps in a variety of flavors to suit input needs, power, bluetooth, etc. You can get out of there for around $200 and then add one of the entry level U-Turns or Fluance decks with built in phono stage. That's a pretty inexpensive investment for kids.
But you could also spend a bit more go with:
The Elac Debut 2.0 B6 for around $250. Pair that with a Denon PMA-600NE or NAD C316BEEv2.
That's under $1,000 without tax/shipping.
