The capacity planning report sounds like a good start. There are also reports that give the most busiest, and least busiest APs. But in the end, having a look on the floorplan/heatmap, and see where clients are located versus where your APs are, combined with some common-sense, will give you probably a good indication.
Please note that you should not mix different AP generation in the same area, so replace all APs in a floor/building/site at the same time.
If you have the floorplans in Airwave, you can also use that to create a predictive AP planning, but finding the best locations for APs based on coverage, capacity and performance requirements is typically done by a WiFi consultant who has specialized software and measurement equipment to create/validate such a design.
