1. Have you tried a direct link over usb?
2. MP3 support is coming in a future firmware update. Not sure about photo, video.
3. AFAIK you can only change your avatar on PS3, Vita, Facebook, not directly from your PS4 . Pain that such a simple thing involves several hoops. I'm sure they're working to fix this right now.
Congratz on your Purchase, welcome to the Dark(er) side :)
