I use GURPS Character Assistant to generate important or recurring NPCs. Otherwise I just include basic stats, like above, a line or two of character description, and any major items being carried.

For generic NPCs it is a good idea to keep a card box full of pre-generated ones: Guard, Farmer, Innkeeper, Bar Maid, Shop Keeper, Peddler, Steet Thug, Pick Pocket, Blacksmith, Carter, Woodsman, etc. Then use a random name generator and you are all set. You could shuffle them into a deck and use them for random encounters too.

Edit: I'd like to have a folder full of generic locations too: Inn, Shop, Temple, Smithy, Shack, Farmhouse, Townhouse, Gatehouse, Guardtower, Windmill, etc. Still working on that.
