Welcome to the fun world of photography.
I feel much the same way as you do

and I've been doing this for 5 years as a hobby (taking about 20k pics a year).
Your photo stream isn't working

At least the link to it isn't! I would love to see some of your pictures!
I think the basics you can start with are things like ISO, shutter speed, exposure, white balance, aperture (depth of field), etc. Those all play a role in how your photo is exposed and developed. First and foremost, learn your camera and lens inside and out. Do you have the 18-55mm kit lens? That's what came with my T1i. For being a kit lens, I think it does a fairly decent job. It's the only lens I've shot with outside of borrowing a friend's 70-300mm lens (don't recommend getting it however).
I would not expect yourself to take professional looking photos right away. The reason I say that is because they are professional looking for a reason...because they were taken by a professional with experience to back them. With that said, you can still learn new stuff to take some really good quality, near-professional looking photos.
Another thing that it is never the camera, always the photographer...something you will hear around here a lot. Some people have a really natural eye and know what to look for...others don't but can learn. No matter which person you are, you will learn and grow and get better and better. I feel so overwhelmed because I see these amazing photos here and I want to be able to photograph like that. Usually I am told that my photos are amazing (not just from friends and family) but coming here, you get down to the real nitty gritty. The great thing is, the folks here offer great advice and don't look down on you for the way you photograph so I say, bring on the photos and they will help you take them better.
I just bought a set of very cheap reflectors from Amazon...cost me a whole 8 dollars...
Amazon.com: 22" 60CM Portable 5 in 1 Translucent, Silver, Gold, White, and Black Collapsible Round Multi Disc Light Reflector for Studio or any Photography Situation!: Camera & Photo and although they are not professional grade or anything, my photos have already improved with them.
Another thing I'd suggest is saving up for a Speedlite Flash for your camera (although the folks here might have a better idea). That way, you're not just relying on your itty bitty not so nice camera flash for indoor stuff.
Good luck and I look forward to seeing your photos! Don't beat yourself up...and don't compare yourself to people who take the wonderful pictures...they didn't take them on their first try, and were in the same position you are at one time.
