Figured that I would try to help out a bit if I can.....
For the shields- Do the Battered Shield of the Fallen Quest. Is easy as heck.... to get the faction do the bear pelt turn-in x2 (nets two decent bracers for each toon.) After this it is just a matter of getting the quest for the shield in Valdeholm and zoning into Frostcrypt. Once there spam "stop or halt" or whatever until the named spawns. Your giant friends will beat on him and draw aggro. Just nuke/dot to help out and the namer dies and you get your shield.
For belts- head to Attiki and kill the genies until a named pops (Hand of blah). You can tank it or root/rot/kite it until its dead (doesn't summon). Uncommon drop will be the Sandy worn sash. You can continue to hang out in the zone and hope for platinum efreeti armor drops (quest will net you a nice mask for your alts). Xp is also very nice.
If you are farming tacvi, then you might be able to knock off the Mshas..... it is more costly, but a less stressful alternative to TSS armor. The focuses are not as good though.
Outside of that I would suggest Relic/ Arcstone for the ear/ring/aug quests if you haven't already knocked them out for your toons. The Arcstone BP clicks are also usable from inventory. I am still amazed that many don't have them. (For the shaman is Spiritual Serenity (baby Halcyon, but casts in .6 secs with a 10 min refresh- very nice for oh shit situations.....)
As far as your raids go, DoN BP and legs should rot fairly quickly, but I would look at Tacvi loot as your source of alt gear.......
