When you ask "next question though, is this variation actually in genes that are on the mtdna? because there are also genes in the nuclear dna where the product is targeted to the mitochondria, so even if the final function/work is done within the mitochondria, the gene behind it doesn't have to be on the mt dna)."
I would say it has to be. Or where would the variation come from? If it was from the central DNA, then that would be the same source code for all. Wouldn't it?
