The 4 link is used to obtain more axle control on the truck and allow the truck to be lifted higher. If you are interested in a 4 link set up I would suggest the OUO Adjustable Link Arms over a 4 link design.

Do it right the first time with the cams and the adjustable trac bar... I went with Truck Toyz BOTH times and they gave me a GREAT deal-FIRST for my 2.5" Icon springs and SECOND for the cams, adjustable trac bar, Bilstein shocks and dual steering stabilizer.
Was the truck aligned after the kit was put on? If not, that ultimately could have been the under lying problem to your tire wear. Not every truck is the same, some trucks need more caster than others to get back into spec.
