We have had the most success when people space our 3-3 1/2 foot trees 20 inches apart. You can space them as close as 12 to 14 inches to create a denser hedge faster. 5 to 6 foot cedars may be spaced from 20 to 30 inches apart depending upon how dense you want the hedge the day they are installed. If you don't want a hedgerow but do want a future windrow they may be spaced 5-10 feet apart.
It depends on the type of shrub. A tag that comes with the plant will tell you the optimum spacing.
Holly, like most plants, is of both sexes at once. And I would say a good three to four feet.

1 yard = 3 feet so 66 yards = 66*3 = 198 feet. So he would need 198 shrubs, but could plant 199 if he went from end to end (see below). If his yard were 1 foot wide he could plant 2 shrubs: at 0 ft and at 1 ft. If his yard were 2 feet wide he could plant 3 shrubs: at 0 ft, 1 ft and at 2 ft.
plant them 12 to 15 inches wide. Keep rows 3 to 4 feet apart.
