Yep, indeed. Just try to cover the basics: thoroughly read the Pinned thread and the first few parts of the docs (you can stop when you get to the Advanced Configuration section for now).
Do the Discourse bot guided parts just to familiarise yourself with the forum software, and bookmark the Cookbook section for future reference.
The fact you’re asking these questions means you’re serious about not wanting to waste anyone’s time unnecessarily, so you’re off to a great start already.
