Well there are alot of keybinding guides here on the forums aswell as on Youtube. You can't copy someone's keybindings since you have to figure them out yourselve. That way you can play comfortable with them.
For my rogue and DK I use a ****load of macro's. Main ones are:
~,Q,E,R,T,F,G,Z,X,C,V. Basically all the keys around WASD. You can use all of them with modifiers. Aka: Alt,Ctrl and Shift. Without the ~ you already have 30 keybindings. You can also use all of the F1,F2,F3 keys etc. And of course buttons on your mouse if you have them.
