Vacuum, Brakes and Smokin'

[imagesinthewind]

Working on the FL car today, Tom wants to drive it more, and am doing brakes, trying to get it to smoke less and checkin out the vacuum.

Brakes: all four brakes look fine, decent pads but front has non-vented rotors. Should they be vented? Should I change them next time the pads need done? Also, the 'Y' vacuum had a tube off, the one that goes directly into the booster. Seemed to make the brakes a bit less 'hard'. But still not as good as I think they need to be. Anything I should look at now? Changing brake fluid?

Vacuum: the yellow 3 way, 1 on top and 2 on the bottom, the two bottom are not plugged in and are even topped off. What do they do, go to and should I replug them into where they obviously go?

Two pack a day smoker. Tried adjusting ALDA but since the smoke is white it's not black, adjusting did nothing for smoking. Not losing oil, still leaking but not like it was on the trip. White smoke means burning oil, right? So the amount of smoke that I see is the car using the oil as fuel? It's REALLY bad. And embarrassing, too.

Oh, and I need to know everything about the NSS. How do I fix it? What does it do that makes the car have to be in N to start?

Thanks for the help!
