low light best practices

It won't affect anything until you go to make a print.

So I will be able to change the dpi if I choose to print?

Most editing apps have a place where you can set the DPI. Change it to what the lab needs, save the file and send it off.

Your shutter speed and ISO seem ok for your camera and the setting. You need a faster lens. Can you get closer and/or find something that has a 2.8 or better?

you're showing in abysmal lighting conditions with a camera not great at low-light, with a slow lens not great at low-light.

free advice: I'd suggest dropping the SS in exchange for lower iso, but a mono/tripod is in order.
$$$ advice: need a faster lens and/or FF camera.

I also suggest shooting RAW and disabling any noise reduction settings, and covert them to B&W.

More free advice: Rent a known low-light performance body and lens.

Image editing apps have an option to change the PPI - Pixels Per Inch.
PPI and DPI are not the same thing.
The image resolution (pixels x pixels) and the print resolution (PPI) determine the size of a print.
pixels / ppi = print size
3000 px / 300 ppi = 10 inches
3000 px / 96 ppi = 31.25 inches
If the image resolution stays the same, a higher value for ppi makes a smaller print.

And 300 ppi is now a somewhat arbitrary print resolution that was a guideline back in the day when even pro grade DSLRS maxed out at 2 to 5 MP, for making prints that looked as good as prints made from film.
