I'd like to know if you can use the server resource pack for a single-player world. If so, let me know in this forums as I will use it in my worlds.
That is not possible for many reasons. The biggest reason it that even if you could get the resource pack on single player, you would not have any of the coding for PokeFind, and you would be unable to play. I suggest that you use a Pixelmon mod if you want to play Pokemon in single player.
