What's wrong with your control arms now.Are they just rusty?
If you start on a Friday night,you should be able to rip everything apart, and have it done in a weekend including painting the parts.Best thing would be to wait for a long weekend.
Make sure you have an air chisel on hand if you want to change the control arm bushings.
Watch out for used lower control arms.The ball joint hole may be oversized and the ball joint won't press in tightly. I had to make sleeves for the holes,but I wouldn't try this at home.
