Have the shirt and was fortunate to do it in a plane made for the job, the C208 Caravan. Can't help you with number one regarding SOPs, but you can certainly help with 2 and 3. Don't break weather minima and don't fly overloaded aircraft. If the crew is incompetent, make sure you're not on that flight. And number 4, with bush flying you learn as you go.
What sort of inadequate training are you talking about? Not proper type ratings, not IF rated. Unfortunatly it's not easy to train someone to do mountain flying or operate from tight strips unless you get some proper line training when you first start. You can read all the books you like.
The worst part of flying in the sticks are the chaps in flip-flops with AK47's over their shoulders and being harassed for money passport etc. But you soon learn to deal with it. Always carry Imodium and a bottle of water, also those wet-wipes. Everyone wants to shake your hand, and hygiene is questionable at best. However, enjoy it while it lasts cause it's great fun.
