Dragondin:
Weapon: Hand of Justice (normal PB)
Helm: Flickering Flame ( normal Bone Visage)
Armor: Dragon (Archon Plate w/ 510+ def)
Shield: Dragon (3os Sacred Rondache +45 all res) - was very expensive
Belt: String of Ears (could also use Nos Coil)
Gloves: Laying of Hands (could also use Dracs, but LoH is so good if you want to do Chaos Runs)
Rings: Raven Frost / SoJ / BK / dual leech (i dont run out of mana very often)
Boots: Gore Riders
Charms: Fire Sunder, torch (20res), anni (20res), (the more attributes the better, but wont affect you too much)

all this and I still have 12 open spots in my inventory, and I'm using GC's with like 23-28 res.
Merc: Eth Andy's w/ 15ias/25-30fire res, lawbringer PB, Last Wish PB, Eth Fort lacquerd plate
This build is expensive, and took me a while to make, but god I love running it. With out tweeking the build it wont be good for ubers, but it wrecks Dclone, and any other boss.
I run around with my resistances at: Fire: 89%, Light: 79%, Pos: 21% and I wreck stuff. I've never had problem or slowed down in players 5 or less. Cows is so easy, just a hot knife through butter. The time to kill goes down in P8 obviously, but I still wreck stuff. I farm chaos, most places in act2, and even world stone. I stay away from tight places like Catacombs and the like, not that you cant farm them, its just annoying to navigate w/o tele, and time consuming. In the time it takes to clear a place like catacombs, you could have ran stoney tomb 20x times. World Stone is probably the toughest when you run into a ton of the poison skelly mages, but if your on p8 you're usually not alone.
Last note, I have recently stopped using my sunder charm unless im going to farm Chaos, or another place where the monsters have very high fire res. Typically my convic aura breaks everything, and boom it dies to the fire aura or one hit from my zeal. Also, you could sub the Last Wish on the Merc for something more practical or inexpensive, but the might aura it provides, combined with 10% life tap is amazing! And I think that the lawbringer is a must, the sancuary aura makes short work of all undead.
For the gear I bolded what I use, and none of my gear is max rolled or "gg", its just what ever the rng gods provided and what I could get my hands on.
Hope this helps!
