Does the Arduino Yun have to be powered exactly at 5V?
It is fine. That is only 2% too high. The microcontroller is the ATmega32U4 and it can have 5.5V. The wifi module runs at 3.3V, and it has a voltage regulator. Some voltage is also lost in the cable. ...

bridge messes up serial.print
Bridge and Serial both use the same pins. You cannot use them both.
Bridge runs at a much higher baud rate (230400 IIRC) than Serial, which is why it all messes up.
