when do you evole your pokemon wtith a stone...?

[BrainWave]

Well, it depends on what version I'm playing:

Blue, Yellow, Fire Red and Hear Gold: NEVER. Except for a few of my fav. though like Haunter and Starmie

The rest, recent games: Except for my mudkip, I evolve my pokemon the moment I can. I evolved my mudkip at about Lv. 60, after beating the E4.

When it learns a move I want it to have.

It depends. For example, I'll level up an Eevee until it learns Bite, then let it evolve. But if I'm happy with the pokemon's current moveset and I know when it'll learn a particular move, then I'll let it evolve.

I will evolve a Pokemon with a stone when it has learned all the moves I wanted it to.

 

[TiTaN.JuStIn]

I don't evolve them as soon as possible. I train it until it has the move I want. Then I evolve it. I got my lesson one day in Leaf Green when I didn't evolve Pikachu at the right time. He was always the first pokemon to faint.
