No. There are many forms of meditation- concentrating on the breath, focusing on feelings of lovingkindness, contemplating the impermanence of all things, visualizing Buddhist personifications or other symbols, chanting things like Nembutsu, Daimoku or mantras, reciting Sutras, writing out sutras, etc. Most, but not all, schools of Buddhism use one or more of those.
Buddhism is such a rich and varied spiritual path that there isn't one answer that covers all schools. However the use of beads (known as a mala in Tibetan Buddhism) is a very common, they are used to count the repetitions of prayers or mantras, they also engaged the body in prayer and help maintain concentration. Prayer wheels, statues and paintings may also be directly used by Buddhists as part of their spiritual practise.
The goal of Zen Buddhism is the same goal as all the other schools of Buddhism, namely, to live life as excellently as the Buddha, in other words, to become a Buddha. This involves experiencing a spiritual awakening (enlightenment, satori) and infusing that awakening throughout all one's activities.
There is no special furniture that all Buddhists use. Some schools of Buddhism have various types of benches for meditation, however. Incidentally, "buddsaims" is not a known word. I believe that the word you are looking for is "Buddhists".
As with all major religions, Buddhism has its own set of practices and traditions. The major practices are twice daily prayers, meditation, and in some cases making offerings to the altar.

Buddhism is divided into a number of schools and traditions, each of which has its own leadership/administration. There is no one person who represents all Buddhists.
Meditation was around before buddhism was even founded. Anyone is welcome to practice meditation, whether you have a religion or not. It all depends on the choice of the person, meditation can be used as prayer, a time to think, empty the mind, etc... so if someone finds meditation useful for them they are welcome to use it. For the same reasons that buddhist's use it for or not. Hope that helped.
Most, but not all, orthodox forms of Buddhism emphasize the importance of mediation. Zen (Chan in China and Seon in Korea) means "mediation." The Zen sect is most widely known in the West as a school that places heavy stress on direct realization and meditation.
They are all the dominant religions of China.
There are no special qualifications for meditation in Buddhism. All that one needs is the wish to practice meditation, and to know a Buddhist meditation technique.
Buddhism has many sects and schools and so there is no single religious leader. Much as the pope may be regarded as a Christian leader, he is not the leader of all Christians.
