The RB VU meter should be enough.

it should be showing movement on the Lefthand set of VU meters if your Recording Properties for the soundcard are set up right for the Mic Input.

It should be hovering and peaking at around the -6dB mark when you sing loudly into the mic.

Sometimes the room you are in imparts its own sound to the mic due to reflections, standing waves and the like. We usually don't notice this when in the room live, but recordings have a way of letting us hear that as if it was accentuated. Usually, more padded things in the room can help.
