You are on the right general track. If you want a more powder oriented ski than what you have - get notably fatter.
The skis you list are all geared towards a modern style, skiing switch in powder, etc. If that is what you are after, then this is a great candidate list ( I assume you mean Bent Chetler). Maybe add the ON3P Caylor. That said, as noted above, I'd err towards north of 120. At your size, the more north the better....
If you want a more unidirectional ski (but still switch capable), just order a Praxis Protest in 187 or 196. IMO, there is nothing better for the mission you describe. Add the fact that coupons can be had to lower the already great site sale pricing by at least 10% and it is by far the best deal in powder skis on the planet (along with Praxis Powder Boards, which are less groomer friendly). ON3P Pillow Fights are probably worth a look. If you insist on a mainstream brand, Pon2oons, Kuros, and Bubbas (more floaty for you than JJs) and similar are worth a look.
For pure powder performance, Praxis Powder Boards and DPS Lotus 138s are tough to beat. But both are more marginal on the groomer end of the spectrum. (hence my Protest suggestion).
Assuming you are looking for a regular alpine binding, your choices are easy - STH 14 or 16, Pivot/FKS 14 or 18, current Jester... All of those are mission appropriate and fine bindings. Do some reading, ask around, and pick your poison. There are a couple others too - but these are easy to find "no brainers".
