GEORGE,
Nothing will beat experience. Start keeping some notes on what you did. Cut depth, spindle rpm, and feed.
Suggest you just try a few experiments ( plunge cut, climb mill on edge, trough the material, etc ). Start with the end mill cutting no deeper that half it's diameter and pay attention to the chips.
I will note that watch out for the small mills, especially as you go below the 2 mm. You can snap them in a heart beat, especially if there is any backlash in the system.
