If I use a Skull Tap, will I need a TRS cable?

It depends. A standard Skull Tap for controlling Tap Tempo on various delays, you will only need a small mono 1/4″ patch cable. If you want to use the Skull Tap Double Control with a Boss RC Loop Station, then yes, you will need one. We offer our Double Skull Taps with a TRS bundled or without one.
