I have no experience with Tuff Country, but their products are comparitavley priced to other lifts on the market. The difference is in the options. The TC kit is just a baic lift (coils, drop brackets, add-a-leafs, etc..). If you compair it to a Skyjacker 4" the price may be double for the Skyjacker, but you also get a lot more (ie: coils, drop brackets, extended radius arms, new rear leaf springs, etc..) IMHO, the Skyjacker kit is the better deal since you get everything you need, better ride (leafs vs. add-a-leaf) and it will perform better off-road due to the extended radius arms.
As far as shocks go, Rancho RS5000's will give you the best bang for the buck, but there are so many others that are available that the decision comes down to the person buying the shock.
