If Kurt only makes one model called T2700, it does look like it comes with an InRide sensor. You'll need the Kinetic app to calibrate it, then you can pair it as a power source. You won't need a speed sensor.

You don't say what your heart rate sensor is or what you're running Zwift on. PCs generally don't have ANT+ without a separate USB ANT+ stick, in fact only older Samsungs phones and tablets typically have builtin ANT+ support.
