Right, You cannot get an pp max in Pokemon diamond or Pokemon pearl nor platinum!
100 is the max there is NO way you can level any further.
There no cheats* that can be activated in the game itself. A GameShark or ActionReplay will allow you to activate cheats. Ex: Max. PP, Max EP, Max. Stats, ect. In some of the first Pokemon games, Red and Crystal for a fact, have a glitch. In Red you can get 100 of anything, and in crystal you can duplicate Pokemon using a masterball. *(That I know of, I have looked on every cheat cite and have found nothing.)
Max out your Pokemon's EVs.
no
It evolves when friendship is max out.

You can get cheats from a action replay max system for DS and DS lite,eg infinite hp during battle, choose your own Pokemon to have that are not available until later in the game like mew, mewto and lucario.
