Hi,
As far as i know, you'll have to write the ASM code (or find somebody who can do it, or learn to do it) , and then you can use orgASM to import it in your Mod.
For the sprite thing, i dig a little in FFTP .493 (havent used it yet) and there is those two fields in the Jobs sheets, at the very right of the last innate ability. The first one appears to be the formation sprite and the second the portrait.
