My thought process was that since the circuit was being shorted, that all the current will go through the short, and none would go down R3.

But when I think about it again.. would the dependent voltage source generate a current through R3?

A reasonable, but wrong, conclusion. All the short does is impose the constraint that the voltage across it is 0V. It does NOT require that ALL the current go through it, just whatever current that must flow through it in order to impose the 0V constraint across it.

Yep.

Do the Thevenin equivalent circuit. This will give you Vth in series with Rth. Then do source transformation, Vth with Rth in series becomes Current Source in parallel with Resistor.
