Depends a little bit on what kind of driving you do. You definitely need the MC. If you're not taking the car to the race track and doing a lot of threshold braking then the prop valve isn't a big deal. (Although why you'd do a brake conversion if you're NOT tracking is is beyond me
) If you are using the car for HPDE or autox where threshold braking is important then yes, you do need the prop valve. Without it you end up with a rear brake bias.
I have the Earl's Hyperfirm SS lines on my car and am thoroughly unimpressed by them. They do the job but the fitment is rubbish. When you're shopping for SS lines make sure that whatever you end up with is coated. Uncoated SS lines can have sand and gunk get caught in the weave and cause corrosion.
If you're more interested in stopping well than you are in bling then just say no to crossdrilled/slotted rotors. Check out the braking forum for more information.
