Shocks and swaybar

My 68 Chevelle has a bit too much movement. Smooth ride but some extra attitude too far past the bumps. Im thinking shocks. Though cost isnt an issue I dont need race stuff. What is a VERY good, shock for front and back. Stiff ride is great. Also it doens not have a sway bar on the back. Is that a bolt on or a welded item. Thanks!

Scroll down about half the page to Chevrolet for rear sway bar...
