Can you plug in a sub-woofer?

Only if your sub feeds your monitors. If you don't know the answer to that question, you should probably start there. This device just provides 2 source inputs, and 2 stereo outputs.

I want to use this to control if sound comes through my headphones or studio monitors. Is the phones out affected by the mute or monitor toggles?

It has 2 headphone outputs, each with their own control, and a knob to choose between cue an input. It is not affected by monitor toggles or mute; those just turn the respective monitor speaker on and off. I run my mains on A and my subs on B for independent control. Each monitor also has its own trim level to manage balance. This thing behaves like any line mixer should.

What cables do i need? i do not know how to set up. i have 2 krk studio monitors and scarlet solo interface. please help

You need 2x RCA to 1/4" cables to connect your Scarlett to the Big Knob, and 2x 1/4" to 1/4" to connect the Big Knob to your monitors. Since the Scarlett is unbalanced out, there's no reason to use TRS (balanced) cables for your monitor run.
