For things like aperture and shutter speed. read the user's manual. Read about Manual mode. I suggest learning how to use your camera in manual mode, it can take a bit to get used to but later you will be getting much better photos than using Auto.
I am no help.LOL. Mine is Digital and has a bunch of neat looking bells and whistles, but I never learned how to use them. So I point and shoot. For Now. I've had this camera for about 7 years.LOL. It's an 8 mp camera. Old as far as cameras go. I need hands on instruction because I suck at following tuts and such.
Good luck and I hope you learn all the things to make you a successful photographer....
Read the manual first. Yes, all of it. Keep it on hand, too.
After that, get a copy of Bryan Peterson's Understanding Exposure. It's pretty much the go-to for understanding the technical basics of photography, it's pretty approachable and understandable, and it's cheap to buy and easy to borrow.
After that, I like Scott Kelby's Digital Photography books as a pretty decent way to jump ahead on the taking-nice-photos learning curve. They're not terribly in depth on anything, but make for good primers in general.
Once you've learned what those can teach you, you're really going to be looking to learn more specific, more detailed, and more in depth things. The best advice I can give for that is to look at the work of other photographers you admire, and learn how to learn from them.
