I am also running into the same problem, and have pretty much the same output as yours (i have changed the uart_clock value and installed Wiringpi).
apt-get update/upgrade helped to get the wifi to work, but not the bluetooth. I have tried to reinstall all my blue tooth related packages - bluetooth, bluez-utils, blueman, bluez, python-gobject, and python-gobject-2. They worked with my usb bluetooth dongle, and still no luck. Whenever I pull up the GUI bluetooth interface, it just tells me that no adapter available.
This is the code I am getting after gpio-v (I am using Raspbian Jessie as well)
gpio version: 2.26

I am pretty new to this so any help would be helpful!
