your *e7* lines should work fine, toyota use the same parts/bolts etc on most models around the same age.

as far as the calipers go, if you dont know what your doing dont pull them appart. brakes have very sensitive tolerances on them and they can be contaminated very easily. the pistons are supposed to be stiff, they seal by precision fit. think about how hard you press the brake pedal and how much force that fluid has coming out of the MC.

captivity of the springs only matters when the cars raised, or if you dont have enough sag in the suspension (i.e REALLY stiff springs) and go over bumps.

so tying them in is a safety measure. but shorter shocks are a better option.
