To start with the basic knowledges:
Shamans are similar to Druids in that they have a rather high nature affinity. Instead of constant shape shifting, they use totems to increase their damage.
Shamans can heal and buff allies, use totems to support allies and attack enemies, and they can also do some mighty potent damage in melee.
Now you should choose a race from:
Alliance:
Draenei
Horde:
Orc, Troll and Tauren
Mana
Shamans rely on something known as Mana to cast their spells. It can be replenished by drinking, potions, or just waiting. It regenerates based on spirit and does not regenerate during casting.
Learning to best use your Mana will be key in defeating enemies as a Shaman. If you use too much then you'll spend more time regenerating. If you try to use too little then you may find you are sacrificing more health to use less mana. Remember though, it's easier to sit down and drink then walk back to your corpse!
Certain totems can be used to regenerate mana. Rely on these when you need to regenerate mana in combat.
Totems
Totems are very unique to the Shaman class. They are the only class that can use totems and are extremely useful. Totems are spells obtained through quests that can summon a "totem" on the ground that does a certain effect.
There are many different totems and each one has a different effect. There are over 25 different ones! Learning when and where to use any totem will determine how good a Shaman really is.
Important Stats 
Since the Shaman can melee, be an offensive caster, or support, the stat choice depends on the situation. Shaman that prefer to melee will usually focus on melee stats, namely strength, stamina, and agility. Support and caster Shaman will usually focus on intelligence. Regardless of which role your Shaman will take, most agree that a Shaman only dies when the mana pool has been depleted.
Strength is used to raise shaman melee damage, each point of strength will increase melee dps by 1/7.
Each intelligence will increase maximum mana by 15.
Each point of stamina will increase maximum hit points by 10.
As a Shaman, depending on your build you will need to focus more on certain stats and effects than others. For instance, if you're going caster (elemental) shaman, it's not unusual to seek out caster gear such as cloth armor in order to improve your lightning bolt effects, and int becomes your most sought-out stat, not strength.
If you're going enhancement, you should focus on the best mail melee DPS sets you can find since you're going face-to-face with monsters. Strength and Agility become your primary stats here.
If you're going restoration, seek out either healing cloth gear or your own mail healing gear, which is a bit rarer, anything helps however. Spirit and Intellect become your primary stats here.
There's lots of ways to play Shaman, you can be melee DPS, healer, or caster DPS, however, don't be fooled into thinking you can tank - you cannot - as Blizzard's level 70 game isn't designed to have a Shaman tanking with mail armor.
