Unless you have a balancer and know how to index u-joints, it's probably just about as cheap to have a new driveshaft made, and you have new, reliable u-joints and yokes.

For the e-brake, pick up just about any floor-mounted handle and fab new cables. You can get suitable wire rope from any big-box store like Home Depot. Plain cables are a bit harder to route than the enclosed cables you see in the magazines.
