If you need to you can weld the upper shock tab to the frame along with bolting it in. Most 4-links have adjustable ends so you can set your pinion angle at the height you want to drive at, called ride height. Once you have completed installation of everything and have determined your ride height take it to an alignment shop to have the fronte end aligned. You may have to try a few places since some are weird about working on bagged trucks.
