How am I going to send the two others in Narshe? Locke? Sabin?

I'm assuming that you're refering to the scene where your characters are split up into three groups: Baron, Terra, and Edgar in one, Sabin in another, and Locke in yet another. At any rate, after completing the scenario with the first three, you will then be returned to that screen with the moogle, and be given a chance to select another character. Upon completing that scenario, you'll return to that screen again, until you have all your characters in Narshe. If you have any specific questions, you can feel free to pm me.

And if you were asking something else, and I'm totally, just explain what you do need to know and I'll do my best to remember that one.

Here's a link to a site that has a semi-completed walkthrough, but it does have that part of the game completed. If you get stuck, you can refer to it.
