[Mad Max] What were they using Max's blood for in the beginning of the movie?

I can't think of a reason. They had water and food. The ones hooked up to the prisoners weren't injured or bleeding at all. The only reason I can think of is that it was some superstition.

Also, why did he have to be brought on the car? Was it that important to not get unhooked?

They laid they explanation out in the voiceover explaining the war and nuclear fallout. This fallout causes a large portion of the population to have a "halflife". these damaged people are also the same people that made up the army of the white painted dudes. They all had some weird tumors as well to visual show this issue. So the used the blood transfusions to stave off their premature death from radiation poisoning.
