I don't think you'll find a specific guide. I've never been a big Corel user (used it years ago for a brief period), but chances are things are not quite as different as you are making them out to be.
Illustrator Group = Ctrl-G, same as Draw
"Node" in Illustrator refers to an "anchor point" or "point". All three names are somewhat interchangeable. I believe this is the same as Draw. The app menus tend to use "anchor" rather than "node".

Adobe's Corel to Illustrator migration guide (PDF)
Around the time of CS2, Adobe specifically implemented some things to make migration from Draw easier. For example, the bounding box in Illustrator was only added to make Corel users feel more at home. It's technically not mandatory for any specific task in Illustrator.
Don't overcomplicate things. I'd suggest simply using Ai as you would expect Draw to be used and, while Adobe isn't always known for intuitive implementation, you may find that you stumble upon many similar features via shortcuts (Group would be a good example of that).
All of Illustrator's shortcuts are displayed next to their menu item. In addition, you can see all the shortcuts by choosing Edit > Keyboard Shortcuts. You can also change the default keyboard shortcuts there to match what you may be accustomed to (although I'd suggest adapting rather than changing the defaults).
