I also see there's a box that the thermostat is attached too, The Trane thermostat is mounted sideways compared to my old one. What's the workaround to mount it on this box?
I think Schlage Link has dropped the monthly fee to $8.99 or $99 per year, but Vera will give you connectivity without any recurring fee.
The C Wire is described as being blue here:

As @stefuel mentioned you'll want to verify what it connects to back at the FAU (heater) before connecting it at the thermostat. It should be the 24VDC common used to power the thermostat itself.
There are alternatives if you can't get the C-Wire working properly, they sell a device to make 4-wires work as 5 (but already have 5). OR you can just power the thermostat by using a 24VDC transformer with the wire run down the wall to pop out near an outlet to plug in.

To cover the hole, I'd consider getting a 2-Gang blank plate or other plastic plate to go between the thermostat and the wall to cover any exposed holes. You can probably mud right over it using some mesh tape and leaving a hole for the wires too.
