Wearing the fronts on the outside indicates either poor camber or harsh cornering.
I've not liked Bridgestone tyres for a good many years. I tried some Duellers on our L300 4WD and they wore terribly, no matter how many wheel alignments I had done (and I even had a suspension specialist replace the torsion bars and spend hours setting it up right and double checking). Bridgestone tyres on my motorbike were a disaster - where I'd get 6,000km on Pirelli, and 10,000km on Dunlop Arrowmax or Avon Roadrunners, I'd get 2,000km on Bridgestone Mag Mopus tyres and have bugger-all grip.
If you were asking me, I'd only put Bridgestone tyres on a vehicle that I was about to detonate in a live-firing exercise.
Even the factory Continentals outlast your tyres - I got 47,300km on mine. Just notched 20,000km on the BFG ATs now and they're still looking strong - and they have good grip too, so it wasn't a trade-off of endurance vs grip.
It does sound like your rear pressures are too high. I'd first try someone else's pressure gauge because 36 isn't that high - we drop our pressures to 30psi for mud and rough tracks. I generally have my tyres around 40psi for the road.
