The picture from the datasheet (on the right), says "Bottom View" - would that mean that I have to mirror it before drawing the component footprint? So Pin1 should be Pin6 instead (for instance)?. (By the way the red is the Top Layer in my footprint)

Bottom view means exactly that: if you flip the chip over and look at the bottom of the chip it looks like the picture ;p Ice-Tea

You must flip the pin numbers.Keep the pin 1 in the top left corner and increase pin numbers anti clockwise.
