Probably not, even for inexperienced users. WEP was flawed but it's been rolled out already and most ISPs configure routers with proper WPA-PSK and long passphrases.
That depends on the router and configuration. There's a flaw in WPS that makes it possible to quickly crack a router that has it enabled, even if it's using WPA/WPA2.
Yeah, reporting the two halves separately is extremely bizarre. It's like they bent over backwards specifically to add a security flaw for no obvious reason. It's surprising that nobody noticed it before it was standardized and shipped.
