OK, here's the basics which you probably know anyway, and these are not in any particular order:
If you're eating a meal with food that needs cutting, always eat with the fork in the left hand and knife in the right. Do not cut the food and then transfer the fork to the right hand. However, if the meal is something like pasta or rice, and nothing needs cutting, it's quite OK to have the fork in the right hand.
Eat with your mouth closed - always, even when chewing gum
and don't stuff your mouth full of food
No elbows on the table
When talking do not wave the cutlery around, lie it neatly on your plate.
When you've finished your meal put the fork and knife side by side on the plate. That way the waiter will know you've finished eating.
Do not slurp spaghetti
Napkin goes on your lap
Don't slurp drinks
If there's a lot of cutlery beside your plate start from the outside and work in
Soup should be sipped from the spoon
Finish chewing and swallowing food before taking a sip of drink
Never put a knife in your mouth
and finally, don't burp, don't lick your fingers, and eat quietly.
