I can give you a reasonable breakdown based on level. I assume you do not have a ton of money to start with. This guide assumes you are playing on Blue.
Do not worry about armor for the most part. Get what you can when you can, but it isn't going to make a huge difference.

The first thing to consider is your weapon. From levels 1-40 you should be doing a lot of meleeing, as white damage during those levels will do more DPS than your DoTs. With slow you can easily face tank most mobs even with basic armor. Here is a list by level of what you should get weapon wise. This changes after certain levels due to the damage caps designed to limit how powerful a weapon is. Shamans use the Priest Table found here:

Levels 1-9:

Levels 10-19:
https://wiki.project1999.com/Guard_Captain%60s_Mallet (If you want to be lazy and stick to Smoldering brand until level 20, you probably could do that. If you want an upgrade, this is about the best you can get for cheap).
Levels 20-29:

Levels 30-45:

Once you hit level 25 or so, you can start killing Misty Thicket Halfling guards along the wall. This is where you should level 25-40, since you can make quite a bit of money there. Each guard drops a 10pp spear. If you are not an Iksar, you can just go into Runneye Citadel and sell to a merchant near the bottom of the zone. When I was doing this, I bound myself right next to the merchant, so I could quickly sell and run back to my camp. Just don't kill goblins to hurt your faction.
If you are an Iksar, or have ruined your goblin faction, you can basically drop swap. What this means is you create a level 1 halfling alt. You drop the bags with the spears on to the ground in a low traffic area, camp, and then log into the halfling alt who is parked in the same location (dropped items only last 6 minutes, so plan accordingly). Then you can just sell the spears with the halfling, and transfer the money back to your Shaman as needed.
The goal here is to get
https://wiki.project1999.com/Ceremon...sar_Chestplate first (if you have the money to buy it before level 45). This will increase your killing speed.
The next item you want to get is
https://wiki.project1999.com/Jaundiced_Bone_Bracer (unless you are an Iksar, in which case you can't use it). Once you hit level 45, this will be the best leveling tool you can buy, other than your Epic. If you don't have quite enough money to buy this item when you hit level 45, and you already bought Ceremonial Iksar Chestplate, sell it. Then buy the Jaundiced Bone Bracer, and re-buy the Ceremonial Iksar Chestplate again when you get enough money.
After that, you want to get
https://wiki.project1999.com/Fungi_Covered_Great_Staff and
https://wiki.project1999.com/Black_Fur_Boots . The Fungi Staff regeneration snares you, so you want the boots to instantly switch between Regeneration/Snare and SoW. Fungi Staff is great for Shamans, because it is basically a Flowing Thought 2 item. You save 1200 mana per hour on casting Regrowth. It can be used at level 35, which is also nice if you have enough money at that level range. Once you are level 45+ with Jaundiced Bone Bracer, you will not be meleeing anymore. I used the Fungi Staff as my main hand item from 45 to 60, until I got Torpor. This is because it is much easier to recast Fungi Staff when it is always equipped, as opposed to switching to it. The stat bonuses you get from having a Shield/Spear will not offset the utility of Fungi Staff. The Fungi Staff also acts as a Global Cooldown Refresh item, so you don't need to wear something like
https://wiki.project1999.com/Shrunke..._Skull_Earring or
https://wiki.project1999.com/Telescope to fulfill that need.
JBB, Ceremonial Iksar Chestplate, Fungi Covered Great Staff, and Black Fur Boots will be your main setup while you keep farming for money. You can basically kill guards until level 55, so I would advise doing that to maximize your cash while leveling. Past level 55 there aren't a lot of money camps that also give xp, so you need to switch between money farming and xp grinding at that point.
The next item you want to get is
https://wiki.project1999.com/Fungus_Covered_Scale_Tunic to replace your Ceremonial Iksar Chestplate. You can sell the Ceremonial Iksar Chestplate, so that takes about 10k off the price tag.
When you hit level 60, you should sell the
https://wiki.project1999.com/Fungus_Covered_Scale_Tunic ,
https://wiki.project1999.com/Fungi_Covered_Great_Staff , and
https://wiki.project1999.com/Jaundiced_Bone_Bracer for
https://wiki.project1999.com/Torpor . This is the most important spell you can get, which is why you want to sell everything and get it first. This spell will increase your power more than all of those items combined.
After you get Torpor, focus on getting all of your spells, including Malo, Pox, and Bane.
After your spell book is complete, you save up for Epic. As you acquire the money for Epic, you can re-buy things like Jaundiced Bone Bracer, Fungi Staff, and Fungi Tunic to help your farming along. Then you can re-sell them again to buy your Epic.
Once you have Torpor, all of your spells, and Epic, you should re-buy Fungi Staff and JBB for situational use. At that point all of the major items and spells are done, so you can then prioritize quality of life clickies, armor, etc.
