The 18-55 kit lens is AWESOME!
I have used a Canon XTi with that lens on it.
It close focus very well and it's super sharp.
It's not going to be as sharp as my 60mm macro because it's not a fixed focal length and dosent have as good of bokeh as my lens.
I think Canon setting is Av for aperture priority. Go ahead and swith it to that setting.
Turn your thum comand dial so that the number reads atleast f/10.
This should give you plenty of focal range.
You can go as high as f/16 if you'd like.
Pop you flash up and go to town.
Remember, give your camera time for the flash to charge.
You might be a bit confused about the whole F/# thing.
Think of it as a fraction. f/4 or 1/4th is larger then f/10 or 1/10th.
The smaller it is, then the les light enters the camera, but you get more depth of focus.
The larger the F/# the more light can enter, but you get less depth of focus.
I really hope that helps you.
