1) worn clutch , leaking slave cylinder , air in clutch line or shagged dual mass flywheel which could also be your noise . maybe low gear oil or shagged box
2) door latch loose (bolted to door pillar) or not adjusted correctly hence door sticks out and slow closing i would guess your door check strap is broken or seized (goes from body to door at front between the 2 door hinges)
3)whistle could be to do with number 1 , shagged gear box and whining or turbo
4)rattle could be anything but does it come from gearbox area or does the rattle go when you put foot on clutch , could be noisy turbo as they can whistle bad when shagged or could be your dual mass flywheel ratling its tits of
5)steering cracks when turning etc could be loose rack bolts as mondeos do the same or could be a crack in the rack itself or worn suspension parts etc maybe broken front coil spring
