Edit: with guild help (just caught that part) you can do the DWB, Glowing Black Rock, Lightstone and Halbard. You may be able to get away with the Earring as well. Since I can't read just skip the rest.
You would not be able to solo Dwarven Work Boots at 26 for the only reason that you have to kill Bloodtalon, Giants, and the ghost beneath Vhalen's Tower.
For JBoots you can solo up to the Nek forest run (if you are using a Wolf Totem, Pathfinding, and/or SoW). After that you will need access to the next zones which require grouping. Once you have access to Zek and EL you can probably do them as well.
First couple parts of the earring quest are soloable (go swim here and see if I dropped my earring...)
Ghoulsbane: need to have access to ToV and 3 people to enter. Once in you don't have to fight anything, just get sword and leave. Only one person can get sword at a time though.
Halbard: Need to kill Ash Owlbears and Skeles by Nek castle and a couple more things...need groups for this.
Glowing Black rock: Only on first part: go here, do this type things.
Lightstone: don't know, I am waiting until they make the quest giving drop a loot item so that I can get it.
