ball joints help

Got the alignment done, sure enough it was the toe that was completely jacked up! The tires wore so bad that they rode like old roller blade wheels!! (worn on the inside and like new on the outer side) one of the tires got down to the steel!! So my next step is tightening the steering gear and hoping that fixes the play but I also need all new bushings. Anyone know how to tighten the steering gear? And which bushings I can do on my own without a machine?
