I'm becoming increasingly irritated at how long it takes to level Restoration. Not a surprise considering the experience gain per casting is only 0.6 points. I want to change this value to something like 1.2 points, but I can't find the settings ANYWHERE in the ini file or the construction set. Is this hard-coded into the game or is there a way for me to change this? I just want to give it a minor tweak, that's all.

I don't think it's as simple as just changing a value.
You''d probably be better off using the Progess mod.
You will be able to tweak ANY skill via the ini.

Open up the Construction Set, select Skills under the Character menu, then select SkillRestoration and change the Use Value for the Hit Target action.

Or you can build your character how-ever you like.
