3 i dont mind the iso noise if it helps tell the story, you would want to steetr clear of it if your presenting a super clean car or a gorgeous girl, but if your shooting a tough looking car in a back alley, or a rough looking subject the noise can actually add to the shot.
4 that filter effect is horrible man. it's good to play with it and see what you can or can't do though. not saying don't try stuff, just saying the end result of this experiment doesnt help tell your story or make your subject look better.
