emvogia - as a fellow switcher I strongly urge you to buy something like the Missing Manual for your chosen version of OsX. It is worth every penny - in 11 months of use it has paid for itself a dozen times over. I now know far more about Mac Os tham I ever did about Windows (though that possibly says as much about the light years between them as it does about Missing Manuals).
Of course, in the interests of commercial propriety I should probably mention that "other Mac Os X hints, tips, pointers and shortcut guides are available".
