Here are my tips on getting Ro armor.
1. Ro armor is a no fail combine so don't bother working on your smithing.
2. You need to be AMIABLE or higher (NOT indifferent) to receive the armor molds. Each quest giving NPC is on a different faction too.

3. Some of the turn in items for molds are tradeable and can be found dirt cheap in the East Common tunnel saving a ton of time (although it is rewarding for some to farm their own). Kilij Plans (boots), Nightfall Giant's Head (Legs), Cyclops Skulls (helm - you'll need a container that holds giant items, the cheapest is a Large Sewing Kit for 1pp) and rotten shark meat (arms) are all tradeable. The giant's head is usually the easiest to find (as people kill the hill giants in WC) followed by the kilij plans (people trying to farm the AC in SRO get this named).
4. Sometimes people sell the armor pieces for less than it costs to make. Besides all the time it takes to gather the items, making ronium requires two platinum bars (100pp+ ea & tip for enchanter to enchant them).
5. The arms are one of the least made pieces. The shark the meat drops off of is in Erud's crossing. You need two and it doesn't drop every time and the mob has a two hour respawn time. I usually took a character I wasn't actively playing and park them there and then kill the shark every two hours. Or go right before bed, kill the shark, get up in the morning and kill it again and hope you're lucky and get back to back meats.
6. At 28 you're a good level to get in a courtyard entrance group in Mistmoore. Good groups clear so well they can reach a lot of gargoyles for your mistmoore granite. Also, they can reach the cooks which drop the cauldrons you need for the breastplate! Be wary, there are two of them in the kitchen and they harm touch!
7. While in Mistmoore, in the mausoleum, there is a bag or flower on top of the grave inside. If you take it and give it to the non-kos npc behind the structure, it gives you temple of sol ro faction. Do it several times as some Temple Quests require faction. It respawns about as fast as you run back and forth.
8. If you look up the undead cyclops in the wiki, there's instructions on how to get him to spawn. It's pretty easy once you've killed the PH. You need two skulls and he doesn't drop it every time (they require a giant container too I believe).
9. If you have a higher level toon, sometimes it's easier to have them do the quests and hand it over. My wizard always did it because he could get around easier and being agnostic, he could raise the factions easily enough.
10. The bracers are one of the harder pieces. The netmasters spawn at the base and inside the tower that Lord Begurgle spawns for the cleric epic in the underwater cave in Lake Rathe. Farm four of them, turn two in for the mold, make the bracer and go back and turn in other two in for a 2nd mold for a 2nd pair of bracers.
11. You can either buy fairy dust (you'll need 4 for each soil of underfoot which you need for each piece of armor) or do a mass genocide of the fairy village in Lesser Fay. The named that spawn there drop wands that sell really well. One turns you into a tree if I remember correctly!
