Hi, Welcome to the bitcoin world!
Yes, this is the place to find out everything you want to know about bitcoins and probably alot you really don't need to know
There is a bitcoin wiki with lots of information.
If you have any specific questions, I could probably answer them (or any of the other people who have been around a while)?
To narrow down... Mining section of this forum is a good start..
Many people do not do mining, so that might not be the best place to start, depending on how you want to use bitcoins.
