68 stepside squeeks like crazy

[wheelspin]

Hello all, new to the forum and classic trucks in general.. I just bought a 68 stepside. I think the first thing I need to attack is the suspension.. hitting bumps and stuff definetly makes the truck squeek and rattle.. I would like to lower the truck some but I think it's already lowered a little so I guess right now I just want to tighten the steering and take care of the noise... where do I start?? I've looked at LMC steering and spring kit for around $400. I assume they have a similiar kit for the rear??
