On a bit of a whim I bought a Canon EOS 20D, I need a hobby! I'd like to take motorsport photos too and some really good piccies on the Oz Rally, so I have 2 months to get any accessories I might need and get practicing.
I went for a bimble this morning and took a few, here's a couple:



Bit rubbish, but it's my first proper camera

Welcome to the world of photography. Nows a good time to learn depth of field, aperture, shutter speed and ISO. Enjoy.
As for your apparent dust issue...
When you take the lens off the camera, and you can see inside; its the flat peice of glass looking stuff you can see inside. Your camera may have an cleaning mode, or you can have it cleaned by canon or do it yourself with special swabs etc. Dont touch it with your finger lol.
The ideas is not to get stuff in there in the first place

- Dont change lenses outside where its windy or dusty.
- only take the lens off to change lenses, dont leave it off when packing the camera
- When changing lenses, swap them quickly so at to reduce the risk.

That's actually the mirror, which doesn't play a part in recording the image. Above it is the ground glass screen, which also has nothing to do with the recorded image but can attract crud which shows in the viewfinder (but not in the image). The bit you may need to clean is the sensor, which is behind the mirror. I don't know if your camera has a 'mirror lock-up' (MLU) facility to assist this.If the camera was new it shouldn't have dust inside, but if it was s/h, it's only to be expected.
As for how to clean the sensor, have a search and you'll find loads of threads about it. Dust shows up most at small apertures and with plain light backgrounds, eg sky, and it will be in the same place on each image.
In addition to Mike's list of precautions, turn the camera off when changing lenses - the idea being that otherwise the sensor has a charge which attracts dust. I change lenses dozens of times for each job, and by following the precautions dust is almost no bother at all.

It's a 18-55 lens at the mo'
most people will probably tell you that's a crap lens (i'm assuming it's this one http://www.parkcameras.com/97/Canon-EF-S-18-55mm-f...), but TBH it will be fine for you until you work out how to use it. I wouldn't bother spending loads on flashy kit until you start to feel limited by what you've already got. read the book, take lots of pictures and have fun!

If in doubt about cleaning it you have a few options
1.) Take it to a pro, people here can recommend places rather than trusting your local camera bloke
2.) You have a Canon, this means you have Digital Photo Professional. This means shoot raw then use the STAMP tool to find the pesky spots and correct, it does a great job. Depending on version you can also map out the static spots and automatically remove them once processed to jpeg.
