Sure, bump your VO track up or the music track down to whereever you need it. The key here is to get it to sound right. Once you’ve got that, you can control the overall dB levels using the master volume. Just keep it below 0 so it doesn’t clip.
As far as recommended levels for final export, I have no answers, because it can differ based on final output needs. I set mine so nothing ever goes above -6.2, but that’s because it works for my workflow.
