One last question:
Can the EOS 400d shot in Macro mode? Is it lens specific, if so will macro be supported by the standard 18-55mm lens?
Macro has a different meaning in the SLR world to the meaning it's been assigned in the compact world. "Macro" in compacts means "close up". That's true in the SLR world too, but there's a subtle difference that that definition misses.
Basically, think of a 35mm camera. Now, consider that when you take a photograph, the lens casts an image of whatever you're shooting onto the 35mm negative (or slide - whatever.) This image, in most cases, will be a lot smaller than the original object. So far, so good.
A macro shot, in the SLR world, means that the image cast upon the negative is the same size as the object in the real world. eg: if you took a photograph of a ten cent coin, and developed the negative, you could put the ten cent coin on the negative, and it would cover it exactly.
This is what's meant when you look at a lens' specifications and it says "maximum magnification": the size of the object's image cast on the film, compared with the object's real life size, at minimum focusing distance and maximum zoom.
A macro lens for an SLR is designed to cast an image that is life size (or bigger; eg: the Canon MP-E 65 can go to five times life size, but that's a highly specialised lens.)
The 18-55mm is not designed as a macro lens - it will not focus closely enough to cast a full size image on the sensor. The best approach if you have no money is to zoom to 55mm, and get as close as you can while still keeping the subject in focus. If you have a little more money, you can buy extension tubes which will allow closer focusing. For more money still, you can buy the 100mm macro, and that's the way that I'd suggest you go if you want to do macro work.
These are limitations inherent in the design of the lens, and there is no way around them without buying more gear. Don't get me wrong, you can still get good shots out of the 18-55mm, but it's not designed for macro work, and trying to use it as such will give you some disappointment.
