One of the best ways to get reagents is have all the mage-related shops in Moonglow (in town and on the island outside the downtown section) marked. There's like 4 or 5 magery/alchemy/herbalist/illusionist shops, plus one of them has the Papua teleporter that arrives in the Papua magic shop.
Even at 20 regs per, one can probably gather 200-300 of each reg per trip, on just Tram or Fel alone, if no one bogarted you out of purchases, without having to hit faction vendors (and if there are faction reg vendors in Fel Glow or Papua, even better). In fact, that's probably where the 60k deeds come from of regs - someone working all the moonglow vendors to 999 - hitting both facets at 999 per seller would put you at about 60k of the ones that are sold by alchemist & herbalist NPCs, 40k for those only sold by mages, in just one trip.
As for Iron Ingots & normal Boards, I do a run-through of Ilshenar. I start at Compassion gate, and check all the random gypsy spawn sites - the path is as follows:
1. NNW to the entrance to the Pass of Karnaugh, to the first random camp site.
2. NNE from there to the spawn site next to the Daemons (by the AW cave mountain's rear)
3. S to the spawn site between the Alexandrella's Bowl permanent camp and the bridge to the undead keep.
4. South along coast, through the mountain pass to the Spirituality area (saves time in the long run, and I occasionally get some horned leather or minor artifacts in the run), through the woods outside the spider cave, to the camp site between the woods and the Inn by Oaks.
5. Run down the road to Mireg/Lakeshire - there are 1 or 2 spots that can have a gypsy camp.
6. Through Mireg, to the spot by the large rock between the Meer town and the Healer Grove.
7. Through the grove, around the mountain, to the docks at Justice - there's a camp spawn there, but it's in the middle of a spawn of 3-4 water elementals. Shopping there is best done with an experienced elemental slayer (weapon, spellbook or bard - or riding a hiryu)
8. Though the woods south, to the empty area south of Mistas. There is a camp site due south of the Mistas bridge, SE of the bridge coming into the open area from the direction of Honesty.
9. Though the Honesty jungle, NW, there is a clearing on a short spur off the right-hand road, that is a gypsy camp. Probably the second most dangerous spot, but tame in comparison to the Justice Docks.
10. North to road end, across a small stretch of jungle, to the clearing between the heavy jungle, Humility Champ Spawn, and Honor.
11. Going up the road, there is supposed to be another camp spawn site near the buildings full of brigands and evil mages, south of Valor champ spawn & Terort Skitas, but I've not managed to catch it active in the last couple years.
12. There might also be undocumented spawn sites across the river, on the road between the Liches and the OTHER side of the Pass of Karnaugh, as well as in the swamp just SE of Humility Moongate, from my distant memories, but if so, they are rare spawns.
Iron workers sell ingots, 8 per to start (I typically by 3k, to average out my expenditure at 9 per ingot), Vagabonds do the same, as well as selling boards at a start of 3 per. One of the NPCs also sells arrows & Bolts, starting at the default price.
All these spots have a banker and healer/mage (fortune teller) NPC, when active; half will also have a forge and anvil. The Iron Worker (smith), Vagabond (tinker/jeweler) and Maiden (Provisioner) NPCs are random - there can be 0-3 of these (1 or each type present, maximum) at each location. So, you can buy the stuff, then immediately bank it. Then, after you're done, go to your favorite bank with pack animals (or buy commodity deeds) and transfer your purchases to your crafting point. The Forge & anvil means that if you are doing the run with a miner/smith (i typically do, since he can drop the water eles in 2-3 hits without even trying), you can loot all the smith type items from stuff killed while shopping, and smelt it at one of the stops along the route. One can also pick up a substantial amount of leather (greater mongbats & swamp dragons), spined leather (ratmen, imps, giant serpents), horned leather (wyverns, drakes) and a few scales, depending how much you have to fight along the way - maybe even arrows from ratman archers or (if evil and they attack you) bolts off meer captains.
I typically bring 9k to 18k iron back from such trips, averaging less than 9 gold per ingot (factoring in the extra ingots from smelting - exactly 9 without smelting junk).
