Hey,
That's great that you are learning a new instrument. There are a ton of posts here that will cover your questions, just scroll down the list (actually, someone else was making the keys-guitar transfer, so that will be really helpful to you).
The frets are those silver things on the neck, BTW.
Just a little tip--you may want to slow down just a bit--get a chord book and get a feel for the instrument, then get on with the scales and stuff (it's a bit backwards from learning piano, I know, but it's easier this way). I was playing for 2 years before I got into scale theory. You don't really use scales to their full extent until you are playing leads.
Good luck. God bless.
