If you put more points into spell spheres it allows the hero to cast higher level versions of spells which are more powerful and sometimes gain extra features. Higher level spells are harder to cast though, so improving Spell Casting may be a good thing to do.

To reverse the skill point, try using this hero editor. Open up the HeroData.xcr in the Warlords Battlecry III folder in My Documents and change the skill points of the hero. I wish there was a way to reverse skill points, even if the player had to pay crowns to get it done in the Campaign :(.
