| As for 1 & 2, I can’t answer them now as I don’t have access to planning software at work (nor does it look anything like work were my boss to glance over my shoulder). I would download HLplanner. It’s free, easy to use and it’s what we used on my ERD course to plan the dives.
3. 100% O2 is often worse than say, 80% as you can switch to 80% earlier (deeper) and breathe it for longer. It’s also cheaper.
(Edit: Just re-read and that doesn't at all answer your question. Air + stage of happy gas works nicely!)
I found the ERD course very useful for oodles of reasons. There’s a couple of hours of kit-phaff in there just looking at your kit and making it more optimised for more gases (adding D-rings, moving regs, where to hang stages, etc) In water skills such as DSMB deployment, stage handling, reg switching was also mighty useful.
