Welcome.

It's great to read of your obvious excitement and wanting to dive in. Dive in with both feet!

I keep a piano app on my phone. There are times I want to play with some licks and don't have a guitar. The notes (there are only 12 we use in Western music) are all there and easier to find in fact as the piano lays them out in a straight line. A piano will help you put the theory you read about to sound so you can hear it.
