I'm sure most Shaman who care about arena PvP have read Push's thread, "Need help in PvP? Ask Push!". It's a great thread, in it he gives some fantastic advice for budding Shaman (particularly enhancement Shaman). The information in the thread is so great, that I created an ebook from it. What follows in an excerpt from that book.
At the end of this post is a link to download the ebook, completely free. All Shaman need to read this, you WILL learn something!
Update 13 Jul: The ebook has been updated to include an introduction
from Push himself. I also removed one image to reduce the file size and
improve download speed.
Update 14 Jul: More updates! I've reordered the advice into 5 chapters (1:General Advice, 2:Gear, Sockets, & Enchants, 3:Spec Advice, 4:Matchup Strategies, and 5:Comp Advice). I've also added some new advice from Push, it can be found in the Matchup Strategies catgory. Enjoy!
Who is Push?
Push is a Shaman on the Dark Iron server. He’s one of the few enhancement Shaman that have been successful in the arenas, regularly posting arena ratings over 2100 without win-trading. He’s been gracious enough to have taken a great deal of time helping the Shaman community improve their arena skills.

If the gates open and there's stealth--on goes the shield. Generally, my Druid goes Bear Form. There are two types of Rogue teams: double DPS and single DPS (duh!). More...
