firstly you'll get some nice depth of field with a f/.28 lens 
secondly there are many techniques to macro togging im no expert and only had my sigma 150mm for a few months.
depending on what you are shooting you will be using f/8-f/16 for some pics especially if you are wanting 1:1 maginification. Be ready to crank up the ISO to keep the shutter speeds up.
I tend ot shoot on Av with exposure compensation as needed. this means i am not worrying about the exposure. and i will tend to keep the shutter speed over 1/250s to remove and camera shake.
for static objects i use a tripod some times keeping a black cloth for flowers may help to isolate subject, stop wind etc...
cable release also comes in handy, if shooting in light boxes then consider your white balance.
it's the most i can think of at this time in themoring!

Patience 
Macro is harder than you might think. Manual focus and move the camera for fine adjustment of focus. keep the fstop set high for good depth of field (around f11) - which means you need good strong light or flash. You will be viewing at f2.8 so the depth of field in the picture at f11 or f13 will be better than you see in the viewfinder at f2.8 so aim to get the focus on the important bit like the bugs eye.
You should find plenty of advice on the forum if you have a search.

Hmmmm, i wouldn't bother. i got one and prefer the bracket flash i made. the ring throws the light well but the reflections coming back from shiny bits on the bugs is a little dissapointing. Its ok for dull things though, i.e.flowers.Just my two penneth.
Sorry for the hijack OP
carry on.....

The closest focusing distance for this Lens is 30cm (which is usually 1:1) from the focal plane - this is denoted by a mark on your camera that looks like a line with a circle through it.
