If I cut the wire to a 5V DC power supply and used the power and ground rails on my breadboard to connect the components to it, would I even need a voltage regulator?

heres the thing the onboard regulator can only supply up to 500mA of current at one time b4 it dies. if you have any additional Voltage regulator, basically you are taking the load off the onboard regulator...

If I use the DC power supply to power this stuff should the ground be connected to the Arduino also or only the components I'm using to draw power from the power supply?

yes connect all the ground .... but be weary of ground looping ok
secondly make all the the component draw power form the power supply and the arduino only supply the signal
