Yes.
What it literally does, is to add the two audio channels together ("mix"), then halves the amplitude.

To set the default sample rate in Audacity, "Preferences > Quality".

I can't test that version as it is so old. The code works OK for me with Audacity 2.1.2 and later.
The current version of Audacity is 2.1.3 and is available here: https://www.audacityteam.org/download/

Much simpler way:

1) Record the guitar (guide track)
2) Record the vocal track (Ensure that "Transport > Overdub" is enabled so that you can hear the guide track)
3) Delete the guitar track.

Why not just record the vocal onto a different track to the guitar?

Provided that you keep the guitar and vocals on separate tracks, you can.
If you "mix" them onto the same track, then probably not.

1) Set the recording device in the device toolbar to the actual device that you are recording from (not "sound mapper").
2) Turn off "Software Playthrough" in the "Transport" menu.
