09+ Eagle and 6.4 VVT delete kit???

So, if I use the factory computer, and a DiabloSport Handheld, am I able to easily eliminate transmission control parameters?

Yes you can eliminate the transmission control. Essentially what they do is go into the computer and select manual transmission. You can then use a 904 or 727 or even a later 4 speed automatic.

And as far as limiting the VVT is concerned, for the DIY Megasquirt and similar crowd, it's worth it...

MS3 allows for VVT. Although I don't know of anyone who has actually used the output on MS3 to make it actually work. You'd be at the bleeding edge so to speak.
