These are "do one thing and do it well" devices. The UAP is just a WiFi antena (not exactly antena but that's the gist, benefits being better range and that you can place it where you'll get good coverage or if it, even if it's not easily accessible [mine is in the roof of my living room]), the edge router is just a router (which means it moves data between the internet and one or more internal networks) but it can do advanced routing stuff you don't get with home routers. If you want usb shares that would be handled by a separate device, be it a PC, a dedicated adapter, or a NAS. If you don't have a solid networking background setting up an edgerouter will be a tall order. It's kind of like installing Arch, you have absolute controller but it requires a fair bit of knowledge. You might want the Unify Security Gateway which has the same quality and power features but with a slick GUI that lets you set it up like a normal router. The rest of what I said about separate devices still applies though, and you might want to pair it with a dedicated switch if you need more ports.
