It's not normal to go through that many parts, either you bought a lemon or your mechanic is mugging you. Or you're buying second-hand or poor quality pattern parts to fit.
1) how have you diagnosed the potentiometer as the fault? What caused the problem with the last two?
2) If they're that worn AND the exhaust is poorly fitted/made then it could cause that, yes.
3) sounds like a boost leak at the inlet elbow or egr, common fault easily fixed with a new gasket.
4) 3 mounts total, engine lower mount (aka roll restrictor) top engine mount and gearbox mount.
5) varying reports on this, i've yet to see any evidence besides anecdotes from the bloke down the pub though. It could cause some minor leaks if the engine has had a hard life, but i'd be surprised to see it cause a serious issue. Fully synth is fine, you're not racing the motor so it doesn't need anything special.
