So I guess I am wanting to be more controlled with my precious exposures and make sure the colours are able to be balanced correctly after scanning, and I figure if I start getting to know grey cards better, I can improve on both those levels?
If you're going that route, you might want to consider one of these:

which works with both film and in the digital domain with Photoshop, which we don't discuss here. dpug.org is the equivalent venue for those discussions.
