It´s a hard stone the piece of earth he asks you for, but it´s not a good idea to change HP that way. He will randomly decrease 1-5 points of every stat of the poke IVs.
This is a good guide to breed HP with non perfect pokes.
And to the other cuestion, most of the best players don´t use perfect comps, usually 2x31,3x20+, only 31´s on the most important IV´s (speed and atk for sweepers, for example).
HP electric Milotic is mainly for Gyarados, it also does good damage on Starmie, Slowbro, etc,.
I run a Gengar with a +spatk nature, IVs don´t matter. 252 EVs on spatk, the rest hp and speed. It OHKO everything besides Chansey, Annoying Magneton´s Tri attack can´t touch them. Shadow Ball/Sludge Bomb/Thunderbolt/Psychic is my moveset. I guess you can pair it with Flygon/Starmie
