Sounds like you need to update your DirectX version. Yes, for reasons beyond our normal amounts of disbelief, Win7 doesn't ship with the latest version of DirectX. You'd think it would, but nooo. That should fix your joystick and wiimote problems.
As for the archives not extracting, that's weird. Try the .exe version, it's a self-extracting 7zip archive (no other program needed), should solve the problem. Also, you should be able to run the 32bit version of Dolphin on 64bit windows without problems, it will just be a bit slower.
Be Happy.
