where can I find a high quality image or images of the entire sky to study?

Aladin (Lite) has a bunch of survey data in various wavelengths and the options to overlay the source names from SIMBAD or GAIA.

And I might be worth looking at other sky viewers, such as Aladin Lite or the Legacy Survery viewer, often the images are cleaner for other surveys, e.g. in unWISE vs 2MASS.
I read that there are high concentrations of interstellar dust and gas near the center of the galaxy that make it difficult to resolve stars. If Earth were orbiting a planet very near to the galactic center, would space appear “hazy” instead of clear and black?

Most of the sky is not full of nebulae, sure, but if anywhere would be dense enough to completely cut off visible light, the galactic center would be that place. And indeed it is! See for yourself - in https://aladin.u-strasbg.fr/AladinLite/ search the "galactic center" and see how it looks in DSS (visible light) 2MASS (near-infrared) and finally WISE (mid-infrared) - as you escape the dust clouds, the sky turns from a dark splotchy patch to a blindingly bright core.

The galactic center is invisible in optical due to dust. If you open Aladin Lite ( https://aladin.u-strasbg.fr/AladinLite/ ) and plug in Sagittarius A*, you will find a tiny handful of stars in front of a dense dust cloud. Switching the image source to DECaPS, you can see a faint red glow as the cloud becomes less opaque in very-near-infrared. Moving just a bit further into infrared with 2MASS, you can see the galactic center showing up in the near-mid infrared bands H and K (green/red). By the time you get to proper mid-infrared observatories like WISE, the entire galactic center is a blinding white, saturating every single band.

I've always liked this sky atlas site for looking up celestial objects. You can zoom in/ out and look up almost any 'static' object (stars, galaxies, nebulae, clusters, etc). OP's object is NGC 891 which you can directly search.
i’m so proud of myself!! i found a constellation by myself for the first time! i’m 13 and i’m dreaming of working for nasa and study stars. i found the Ursa Major!! i also saw a shooting star! i’m so happy!!

Check out the Aladin sky atlas. Can pretty much type in any constellation/ star/ nebula/ galaxy, it'l center to it then you can zoom in.
