I'm a beginner and I was wondering what the most basic "need to know" chords and scales are.
Basic Open Chords,
Barre Chords,
Power Chords,
Major Scale,
Minor Scale,
Minor Pentatonic.
+theory for all.
If you learn the basic major scales you can take that scale and just by looking at it turn it into a minor, harmonic or melodic and tons of other stuff. Just by learning the major scales you can do so much to it

I feel we should go to...

Purple Alert
start by learning the major scale and how chords are formed, intervals and stuff like that
been there, done that. NOT,NOT... respectively
