A tripod will be a big help I think, 2 sec timer if you don't have a shutter release cable, you want to keep your ISO low with that camera.
Think about lighting, think about your background (nothing worse than taking a load of shots, then realising there's a dirty mark or a distracting object in the foreground or background, likewise dirty plates, crumbs etc). Look at some magazines/cookbooks etc and find shots you like/the owner likes the look of and copy the style of those.
When I've photographed food I've cooked I'm always against the clock because I'm hungry and I want to eat it before it goes cold. But for this it's less important, so you can take your time. You can obviously practise at home with a salad or a sandwich on a plate. You can stick a couple of desk lamps on either side out of shot.
Remeber light gets harsher/harder with more shadows the further away it is, closer=softer.
Once you get a good setup though you should be able to swap plates and do the shots quite quickly.
White balance will be important so shoot raw or make sure you've got a good WB set.
I find the opposite to be true with food. I'm using a larger sensor camera and wider aperture lenses, but find myself wanting to stop down for more depth of field as while it's not macro photography you're focussing very close.
It's not like portraits where you get the eyes in focus and sod everything else. steak and chips or a bowl of soup doesn't have any eyes if you're doing it right (rib eye has one eye...).
