How can I attach 25 feet of quarter-round oak molding to drywall?

What kind of nails should I use? How long should the nails be?

Do I pre-drill the oak molding? (If "Yes", should the holes be
smaller than, larger than, or the same diameter as the nails?

(I don't have a nail-gun and I wouldn't buy one -- or a brad-nailer --
plus a compressor for such a small project).
