Before you get clubs, find yourself a golf clinic. These clinics give basic lessons to beginners to get them started in golf. Often, the people who conduct the clinics will lend you clubs to get you started.
A golf pro at one of these clinics could help you decide what clubs you need.
Too many beginners - and unfortunately lots of people who have been playing for awhile - think of golf clubs mainly in terms of club heads. Half the club is the shaft. The shaft can vary in length, stiffness, weight and other qualities. You want to make sure you get a shaft that fits your swing.
