Dude I just finished a marathon swap of my rear end putting in Moser 33 spline axles, spool, c-clip eliminators, strange 10 way shocks, coil overs etc, steeda adjustable arms, moroso drag shocks, and weight jacker control arms! You can easily do it yourself just make sure the car is well supported with proper jackstands, you have ample room to work and have a good jack. Also some concrete or wood blocks will aid in the removal and installation.
Spray a large amount of penetrating fluid on the bolts and let it soak. Work the bolts with a breaker bar back and forth and before trying to lossen them, turn them to tighten them first. This will break losse any corrosion. If you go hog wild on old bolts you stand a good chance of snapping the heads off even on grade 10 bolts. Ask me how I know. Do you have an impact gun? if not a johnson / breaker bar and socket on one side and a wrench on the other.
E-brake cables are easy, you just have to bend the clips in on the cable at the brake assembly and push it through the backing plate once you get the drums and shoes off. If you have never done brakes before take a picture of it before you take it apart.
What are you swapping in?
