there is no need for these imo.
hammocks are just gimmicks and far from essential (unless your planning on going to a rain forest)
a stove isn't necessary as surely you will be using a fire? but if a fire isn't possible (not allowed or too wet) i would go for a trangia stove. runs on meths, much lighter and has no working parts to go wrong. you can just use the burner on its own with your billy can suspened aboth it as you would over a fire.
if you cannot rely on your own navigation skills you should not be out! GPS systems break or run out of batteries and if you can only navigate with a gps your in trouble. learn to use a map and compass before you plan any trips.
you dont need to carry sterilisers if you can boil water. although a milbank bag is a good .
i used to carry a leatherman but soon learned that they have very little use outside of society unless you carry complicated equipment like the pressure stove you suggested. keep it simple is the rule - complex equipment can make your life much easier but can also make your life much harder if it goes wrong.
SHAVING!

that is almost blasphemy in bushcraft!

seriously though, you can go without shaving.
i never bother burying my poo, animals don't so why should i? its no different. there are other times you mite need to dig such as foraging roots but a digging stick is more suitable and you dont have to carry it with you!
hope this helps, other will disagree but i think in bushcraft you need to loose as much reliance on equipment as possible.
have fun!
