If you are using the crafters mainly for housing you should consider taking up ALC as well as you get aaaall the plant stuff from them. Wall Planters, Planter Partitions, all kinds of potted flowers, etc.

Also - CUL has some sweet tabletop items and is one of the easiest crafters to level. I would just take it one by one. Look up leve guides, ask other crafters to help you out with HQ items for turn ins. Do your daily GC turn in and don't rush it. You are not in a hurry.
