Do I need a usb to uart adapter if i have a teensy or the Arduino Leonardo

When using a bluetooth dongle you need a Teensy (or similar), but you don't need a USB to UART adapter.
An Arduino Leonardo can be used to replace the Teensy. But it's not compatible with the Teensy loader, which means you have to find a way to program it (the official Arduino software does not allow to upload hex files). You can try with the Arduino Builder tool, but I can't guarantee it will work, and you may not be able to upload any other firmware after that...

Thanks for the help

What HEX firmware files do I use for the Arduino linked before?

The Leonardo embeds an ATmega32U4 chip.

So do I not need to flase any new firmware?

Yes.

You can use Flip to flash the Arduino.
