... I cannot bounce the light because the ceiling and walls are very dark.
Don't always assume this.
1) Is there an online source you'd recommend (even an audio book), or perhaps a series of videos that would help?
Neil van Nierkerk's Tangents website is for on-camera flash what the Strobist is for off-camera. It also comes in book form.
2) Should I get something like the MagMod, or the Gary Fong system to better do the job?
Of the two, I'd go MagMod, just because you have a wider choice of modifiers. But the tupperware dome-type things are going to throw light out in all directions, vs. the bounce card/scoop-type and still be relatively hard (small size). A flashbender or maybe the fstoppers disc (if you use the flash on a TTL cable) might work better if what you're after is less hard light.
Ideally, if you can, you get into off-camera flash.
If you can bounce, I'd recommend van Niekerk's BFT flag.
3) Should I look into getting a newer flash to take advantage of a newer camera?
I won't be using anything else but the camera-mounted flash, so off-camera options won't work for me.
The 580EX's main drawback with the newer camera bodies is that it can't communicate with the camera via the flash control menus. The 580EXII can. But the current Canon flashes are mostly about also having built-in radio triggering and more off-camera flash features (groups D&E, Gr mode, using flashes as remote shutter releases, etc.) and you say you aren't interested in those.
But your 580EX is still completely compatible with your camera, and for on-camera use, you aren't necessarily going to see much difference, other than having to make settings on the flash itself rather than the camera menus.
You also don't need to go OEM to get menu-communication. The newer TTL 3rd-party flashes, like a Godox TT685-C or Yongnuo YN-600EX-RT or YN-568EXII can do it, too.
