I think it's easiest if I just send you my premade Index control scheme.
Select Znix or Rokk's bindings under community bindings. Then go to PAYDAY 2/mods/saves, and replace the contents of "vr_improvements.conf" with the contents of this pastebin:
https://pastebin.com/DNHX510F

this should give you smooth movement on the left stick, and smooth turning on the right. weapon firemode and gadget switches are on the index face buttons, though you might need to two-hand your weapon to toggle the gadget.
