Need some more info. How much lift are you looking to add? There are some parts you can add alone other you have to do in groups. I would start by deciding how tall you want to go as that will help you with what other parts you need.

Otherwise - you are going to spend weeks organizing all the needed parts, and still might miss something 3/4 way into the project. I helped a buddy do a part by part lift, and it was chaotic - I am a firm believer in kits, and if you have a specific vendor part that you want to use, buy it, and sell the one out of the kit.
