I recently got this MMA8452Q accelerometer Breakout board and I am not sure how to connect into to my Arduino Uno. Only really know where the power and the ground go. Explaination would be nice, pictures better.

Thanks in advance.

(Sorry, if this is in the wrong topic I was not sure which one it would go in.)

You won't be able to use the default Wire library to communicate with this accelerometer.  This accelerometer needs a repeated start between send and receive, which is not supported by the Wire library (actually they just patched this problem but I don't know if it's released yet).  You can read about an alternative here http://arduino.cc/forum/index.php/topic,80897.0.html
