Hey Jeff,
Certainly a clear answer :o) I assume that you use After Effects already?

From my point of view, besides the very basics, I would invest time in anything that belongs to the “MoGraph” part of CINEMA 4D, and the way After Effects is connected to C4D.
I would suggest to go through the Menu MoGraph, and explore each object from there. Click on the Tutorial tab here in the interface, then there is an option “Latest Tutorials: (x) show all” click on the “show all”, to enable the options in the left area, like “Diciplines” and “Utilizes”, etc. By default it filters too much ;o) ...or use the Search. (I give you here a short list of themes to have some terms and ideas to start with.
Modeling is of course as well part of this field, but I would focus during the start mainly on the options given to import from Illustrator, to create Splines, and how to produce objects from there.

My believe is as well that this field benefits from a good understanding of light and camera work. Which leads to animation, where any knowledge from After Effects will support you here. (Learn it from the scratch -keyframes,—F-Curves, avoid supporting tools or plug ins, they will limit you on the long run.)
Broadcast Graphic, if I understand that correctly, is a subset of Motion Graphic. Certainly a field in which texturing is an important part. Texturing means, how to use the options in the “Material”, and to get clear about the projections (the way textures and shaders work on the surface).
I know you asked to start from the “ground”. The Quickstart Manual, the tutorials in the Help Menu, as well the MAXON Quick-Tips, should be known. Nothing that takes too much time, but certainly worth it, besides anything that you will find here.
The mix of these should give you a good start, and if you see something that you would like to re-recreate, you might send a link of a video and ask. Motivation and curiosity is certainly the best way to learn C4D. I like to help there.
Just a default note, I like to use the forum (no pm’s no e-mails) so many people can take advantage from it. There is not “stupid” question as one mentioned it today (about his own post, which wasn’t in that way at all of course), or something “embarrassing” to mention, as well a quote from today. Only arrogant people believe they know everything, and I tend to ignore such people more and more. Exploration and playfulness have certainly enriched this field of work more than any opinion about it.
So, please ask, because anything that is not cleared for you, will limit your success later on.
YES, there is certainly more to that field you are targeting, but the package I have given you already is enough to start with.
Good Luck
Sassi
