Because lists of gear are very useful, I've been keeping my eye on several places to get a good list of places to go, quests to do and crafters to hassle for resto gear. So in no particular order here they are:
- WoW Loot Kaliban's Shaman list. This is a nice list of good Shaman items which can be gotten from TBC 5 man instances and quests, broken down into Elemental, Enhancement and Resto. I usually go from the bottom up, starting with quests in Netherstorm, comparing to my gear and noting the quests to do. I would advise not to stop too soon either; initially I only looked up to BEM and then last night was surprised to receive Metallic Headband of Simm'onz as a quest reward in Nagrand.
- Matticus' recommended pre-raiding checklist for the Restoration Shaman. I have previously found several of the items from this list by checking WoW loot, but thanks to Matticus I've discovered I don't have the crafted White Remedy Cape and moreover someone in the guild can make it. There is a good discussion about which gems to use as well, whereas WoW loot doesn't really make any recommendations about specific gems.
- WoW Insider's Totem Talk Column: Stuff to wear to kill stuff in Karazhan Pt. 2. Despite the huge title, this is another good list of Resto, Enhancement and Elemental gear items to get pre-kara. There is a Part 1 and should be future parts. The article doesn't go into a lot of detail about where some of the items drop, but wowhead links are provided so you can find out yourself.
