Your best bet to farm yellow scrips is wait for every weekly reset and do Zhloe/M'Naago Custom Deliveries.
If you need them desperately, the crafts for the collectibles aren't hard to make, but they generally require extensive farming, and some of the mats are from nodes that only spawn to you if you have the folklore books, which are another grind in itself.

Either ways, get rid of the Ironworks gear, it's severely outleveled by even SB's leveling sets. The current best is the Ala Mhigan gear. But if you can't afford it (which is likely the case), the 290HQ gear/tools are good (the off-hands and accessories are still BiS) . Also, don't bother trying to farm the 300ilvl yellow scrips main-hands, the 290HQ ones are much better, after melds.
