I am unable to properly connect those things together with batteries:

Arduino Uno
Parallax continuous servo
Arduino wifi shield

5xAA batteries are connected through power jack to arduino which I assumed would power both arduino and the wifi shield and then I have 1 9 volt battery to power 2 servo motors.

With this setup it seems like I can only get to run 1 servo at a time.

Here is a picture how it looks like: http://imgur.com/0jtbPHT

I'm really desperate for any advice/guidance when it comes to powering this thing.

    9v is too high for servos and risks destroying them. 5x AA is not enough for an Arduino's input except when they are new. – Chris Stratton May 16 '16 at 15:48

9V batteries can only supply very little current. So two servo's is too much.

Just use another set of multiple AA batteries for the servo's.
