I'm not a huge fan of PVP, so I farmed them. If you can get the Symbol of Avarice and the +3 covetous gold ring, it shouldn't take too long. Took me two days to get all the Proofs of Concord Kept from the Silver Knights on the stair case at Anor Londo, but that's the worst one (because to get the achievement for miracles, you need the Darkmoon Blade spell, and to get that you need all 30 Proofs). The others are a bit easier. I farmed the Pale Tongues and the Swordgrass from the darkwraiths, etc. right outside Abyss Watchers (they do most of the work for you). That only took a couple hours). And I got the Human Dregs from the 9 Deacons on the overlook right past Pontiff bonfire. That drop rate sucks, but you only need 10. For Sunbro and Moundmakers, just find a friend online and mow through a few bosses to get all 30 Sunlight Medallions, and the Shackles are easy to get simply by summoning and killing your buddy (need a few embers for this).
