Monkeywalker, this is a job for a pro I'm afraid. Even if the inlays are identical to the ones in there, the board needs to be defretted so they can be inserted and sanded level with the fretboard radius (they will be flat out of the box, not radiused), and then refretted. If they're not identiical you need a Dremel Router set up and jigs to rout out the cavities for the inlays.
