Don't want to be an arse but use the search maybe? Theres been hundreds of people asking the exact same thing. In answer to your question, Hubs and headsets go on how much you want to spend, If your minted go for Chris King - last for yonks and have a great guarentee (on the headset anyway) Although For a newbie it doesnt actually mean your poor so cheaper parts could be canecreek headsets to onza hubs etc. But if you want pimp parts go for deng as their basically in the middle of the price range.
