To jump to your questions:
xD is a memory card format, the smallest available (the one used on phones), it is compatible with SD so you can actually use an xD card on a camera that takes SD cards as long as you have the adaptor (usually sold with the card). It is slower, so I would stick to SD cards. SD means Secure Digital, btw (by the way).
ISO rates the sensitivity of the sensor (on film you would buy an ISO 100 film for sunny days, ISO 200 for overcast, ISO 400 for indoors... as general rule, etc.) As the ISO goes up on film, the grain gets bigger, on digital as the ISO goes up the noise increases. Still, today's best cameras cab push the ISO up to several thousands and still give better results than most ISO 800 film. Next generation of cameras coming out by the end of the year will be even better. On film you are stuck with a certain ISO for the entire film, on digital you can change it as much as you like to get better shots.
SLR means that when you look inside the viewfinder you are seeing through the lens that captures the image and not through a separate lens like it happen on non-SLR cameras. So you're actually seeing through that expensive piece of optics you purchased and what you see is much closer to what you get.
Feel free to ask anymore questions...

Yes, but don't limit ISO change for that. For example today was a very bright day but I was shooting pellicans at ISO 400 to get a faster shutter speed (light sensitivity increase = shutter speed increase).
It's great to have a high school student here. Learn as much as you can while you're young, it gets harder later... :-p

But what I would look for is some books on the types of photography you are wanting to try and capture. Most of them explain all of the basics like Shutter Speed, ISO settings, F-Stops, blah, blah, blah... I still carry these books around with me as a referance when I am out taking photos.
The other way that I learned was to just play with the settings on my camera. I would take a couple of shots then change one of the setting weather it was the ISO, Shutter speed, or the F-stop. Then I would look a the differences in the shots and take note of what changed.
Trust me when I say I know how confusing all of this is but stick around here for a while and you will learn tons of great stuff. Everyone here is more than willing to share any and all of the information that they can.
Just remember to have fun, if you get frustrated, walk away for a while and come back to it and eventually you will have what I like to call an AH HA moment.
I hope this helps.

"National Audubon Society Guide to Nature Photography" by Tim Fitzharris
"Nature Photography Field Guide" by John Shaw
They both have a lot of great information, and really do a great job of explaining things so that beginners can understand. They also cover a broad range of photography skills such as Macro, Landscape, Exposure, Motion Effects, and a whole lot of ofther useful information.
I have really been looking for a work book that has exercises in it but, I have not found one of those yet. How ever since we have started the Weekly Assignments here, I have found that is helping me a lot more.
I really hope this helps, and like I said if you have any questions what so ever by all means ask. Everyone is very helpful here.
gldiana wrote:A book I think would help you a lot is National Geographic: The Ultimate Field Guide to Photography, you can also get it used for about half price (~$7, well spent). This has all the basics and some more advanced stuff that will come handy for a long time. Another way to improve quickly is to take an online course if you can afford it (I am starting an 8-week course today with best seller photographer Jim Zuckerman).
Shooting Quality (Resolution): always the highest. Remember: you can scale down but you cannot scale up (without losing quality).
Aspect ratio: DSLR usually have a locked aspect ration (4:3 or 3:2 depending on brand), which is dependent on the size of the sensor. 16:9 is not a photography ratio. What camera are you using? Rebel I seem to remember...?
