Yep, you are on the right track. As long as you are not getting crazy with the lift of the cam, the stock springs/ lifters/etc. will be fine. The reason I suggest the PAW route (performance Auto Warehouse) is that their house brand cams are actually Crane Cams in a different box. (I lived in Daytona Beach where Crane is based, and saw pallets of cams coming right down the assembly line, going into plain white boxes slated for PAW, and I have bought a few from them, and a Crane timing card comes in the box,)
Call someone like Crane, outline your car and what you want it to do, and they will give you the specs you should use for a cam. Then take that info and shop. The key to good solid HP is a balance of all the add on parts, cam, intake, carb, exhaust, etc.

Don't get nuts with the cam and carb setup, and you will have a better running car with good performance, economy, and reliablility.

Just my thoughts on the subject.
