whoever can hit a drive 280 uphill but cant hole the ball from 20 yards in AT MOST three shots is definately spending his time at the wrong practice site. Leave the range and start working those par 3 holes.. Besides, thinking one would need 5 wedges is a bit much in my book.. Most guys I know prefer to get comfortable with 3 or at most 4 wedges, with a couple of them that carry only two..
the 3 clubs 9 holes thing reminded me of a "drill" my old pro gave me a long time ago. He basically confiscated my clubs and left me the 7 iron and a putter, and the message that I could get the rest back when I broke 82 in a club tournament. He did the same thing a half year later with the 4 iron instead, which is a bitch to get out of greenside bunkers

. the main thing that it taught me was to be VERY creative with my irons, to this day i can vary the length, height and curvature of a shot because I needed those shots then(and a sort of flop shot with the 4 iron, which isnt very usefull except for training some "feel" for shots).
iammatt's remark about the driver holds true for me as well, a normal drive for me is 230m carry, 240, 250m total depending on conditions. Which is more then enough to play most courses in these parts.
