There are many sources for Kitchen Aid Mixer recipes.  You can use basically any recipe you find.  A tip is that you want to use the paddle attachment anytime you are going to cream butter and sugar together and make some type of dough (not most breads) or batter.  You will use the whisk attachment when beating egg whites or making whipped cream.  This attachment puts air into the food and adds volume.  You will use the dough hook primarily for making breads.
