32 spokes laced 2x make for a less strong wheel compared to lacing 3x.
This is my spoke-length calculator of choice:

(if using that one, make sure to click on the "Help" tab to see what is measured and how exactly)
For the rear hub with a cassette, make sure that the NDS side spokes are at least 1 (to 2) mm shorter than the DS side spokes.
It will help you get the wheel dish correctly, without risking having either NDS, or DS side spokes having less than complete thread engagement.
If you can afford the swagged spokes, I'd go with those (2.2 - 1.8 - 2.0, or 2.0 - 1.8 - 2.0) for both the DS and the NDS.
Having said that, it surely makes sense to use thinner spokes on the NDS, but with modern double-walled relatively strong rims, and only 32 spokes, I prefer the extra durability of the swagged spokes on both sides, while it's still possible to get a sufficient NDS spoke tension to prevent them from loosening.
