respeccng questionFollow

I am currently a level 66 hope to change that soon in a bit, anyway, I wanted to respec. Get rid of some of the stupid things I chose, and improve on ones I did, but not really change. I want to stay demonology. And I actually like my demon's names, Domethea and Thugthang are awesome names, plus it would be weird seeing another name. So if I respec, would their names change? And would I have to rebuy all of the "skills" for them again?

Thanks

Sweet thank you so much :)
