This doesn't exactly have anything with Mission Ideas to do with, but here we go...
1) No idea.
2) I've never used the misson wizard for editing purposes, but I have played that mission in it. Basicly, what it does is that it lets the player decide how the mission should be designed. You put out bases and patrols, assign them to a marker and when the player loads up the mission he can decide where the bases and patrols should be. Quite cool actually, but I've never seen a mission using this idea, which is rather sad.
