Do I _really_ need a 2nd coat?
#1

I have a new house and am painting one of the bedrooms (pale green semi-gloss over the flat bone color which the builders used throughout the house). My first coat appears to have provided good coverage. Is a second coat really necessary? What are the benefits? (durability, etc.) Thanks for your help.

Mike is right, if you are happy with it then there is no problem leaving one coat, however, when it comes to gloss, semigloss, eggshel or satin(especially eggshel and satin), in order to get the full sheen and depth of the sheen and color, 2 coats is required. If you was to go and paint one more coat on one wall in a room, you will notice a sheen and depth difference and if you do this be prepared to go ahead and paint the other 3 walls.

I noticed some bare spots (wall is textured so it is hard to get it all on the first coat) so I went ahead and did a second coat. It does appear to have better sheen. Thanks for the info--it will be very useful in the future.
