Hello!

While I've downloaded Godot and have planned to use it, I've never actually did.   I want to know if anyone has good advice on how to quickly learn the ins and outs of this game engine, just enough to make a semi-functional game.  I'm also curious if there are any recommended plugins and addons for the engine.  Also, good luck with your own project!

I'd suggest you to read the documentation, it's very well written: https://docs.godotengine.org/en/stable/getting_started/step_by_step/index.html

They also have some step-by-step examples and after that some tutorials. Spend some time reading it and you should be ready to go

Godot Docs https://docs.godotengine.org/en/stable/index.html almost always has the best stuff, its the best documentation I've ever seen. Questions should direct you to Reddit, StackOverflow, Youtube, or https://godotengine.org/qa/. Good Luck!

Heartbeast and GDQuest on youtube are great, online, you might be able to find some quick snippets on kidscancode, the qna is good if someone has a similar question to you, and of course, the docs.

In addition to the great resources posted so far, I'd say is through experience. Don't get stuck on tutorials. Try to make something simple and small for the jam.

 I learned the basics of Godot over a weekend-long jam. I however have some background in programming, and everybody has their own speed of learning, so don't get discouraged if your progress seems slow.

there are some things which u need  to practice . but the basics should be easy to understand.
