Ady I don't know where you get your energy from.
There is I imagine, a bit of a crossover (if you clean up a HD version of the post DVD cut making a version of the Theatrical cut is, in theory, made easier) and both will possibly help you eventually when you come to do your TPM:R.
But it's still work on work on work.
As grateful as we all are please don't burn yourself out.
