It's okay to ask questions. That's how we learn.
Trish has added tons of information in the form of 'Stickies' in the Welcome and Help Center. I would suggest you start there. After that, just take your time and learn as you go. It's a big, beautiful site and it will take some time to learn the ropes.
Edited to add:
I forgot to say that if you use Control F with a key word as you search pages you can find what you are looking for without having to read all the words.
