Another Magelo for reference. This is all EC buyable gear at 20k or less per slot (most of it is far less than that, just noting since a few items can get that high). There are plenty of quest items a non-raid shaman could do to really fill it out and have a solid set of gear. This is with 105 sta 105 wisdom at char creation. I was able to get to 206 stamina and my wisdom still falls plenty short of 200 (using 200 as reference since the amount of mana per wisdom drops at 200).
As illustrated a non-raid geared shaman can easily cap stamina with buyable EC gear. With questing more items over time (Scout for Talisman of Benvolence, Circlet of the Falinkan, etc) you could get better raw hp/mana items and increase your wisdom a fair bit. It also doesn't account for more expensive MQs like SS BP/Legs, which a solo/small group non-raid shaman could farm plat for and buy eventually, which really would give the build a boost. I also left JBB in since it's probably the best bang for your buck DPS option on a non-raid shaman, since your gear options might not always allow for sustaining mana for your expensive dots while reslowing/torping/canni dance, etc.
