In the following chapters you will learn the basics, get recommendations for different levels and purposes and get a good idea how to get the necessary items.
Armor: On most servers there is a lack of capable healers on both factions. This said a healer is probably going to lead to the most (returning) group invites. For this purpose you want to focus on int/sta/healing items to play this role with a maximum of efficiency.
Usually though at lower levels the +healing items are not that great and you will be better of with stamina, hit point and intelligence gear till your 50ies.
The basic green stuff that matches grouped equipment requirements is the eagle armor (xyz of the eagle). It provides decent int/sta increases when you can not get your hands on any specific quest rewards or blues.
If you are going for feral (solo) equipment the equivalent would be bear armor. Another advantage is that you do not waste any time browsing the Auction House or trade channels.
