I think you've got things a bit upside down... horse before the cart perhaps?
1. Trainer kite, learn to fly it. Wind window, power zone, etc.
2. Water kite, rigging, safety systems, body dragging, self rescue.
3. Water kite + board, up and riding, etc.
You don't use a trainer kite on the water, and you don't use it with a board.
You do use a trainer kite for practicing flying and learning the wind window.
2-3m trainer kite is perfect. Get it on a bar if you want to use it as a learning aid for kitesurfing. Get it on handles if you just want it for having fun.
While I agree with Koma, I have some extra stages;
1- Buy
or download one of the instruction DVDs
2- Get a trainer kite
with bar and trust me, you will need it more than couple of hours.
3- After you learned everything about the first 30 mins of your DVD go and book time with your instructor (this way you wont waste your instructors time and you will get the maximum benefit out of your 2-4 hours)
4- Get advice from your instructor on which kite to buy
5- Practice a lot of body dragging (it's the start of the fun)
6- Call your instructor and ask him what size board you need.
7- Come back here and call us noobs and give us red thumb
