After Book 14 went live ALL the reputation crafting recipes are available to buy from the NPC's who give the reputation crafting quests. (So much for all my research.) You may even purchase the recipe for stuff you don't have the crafting level to make (but you can't "learn" the recipe). You do have to have the rep to get TO the vendor (Elf, Dwarf) but don't have to be any particular rep to access the NPC's store. You can even use the recipe (if you have the crafting level) and learn the recipe and make the rep crafting items, even if you haven't done the quest for that item yet. My level 37 GM scholar made a stack of 50 "Mysteries" which eventually will be worth 35k rep points! (I been saving up.)

Here's the catch: You cannot barter the crafted items for reputation points, I guess until you have reached the appropriate character level and done the intoductory quest. You get the error message, "You have not done the prerequisites to barter this item." (or words to that effect). So you are just going to have to store the crafted rep items until you have reached the levels I described in the above post and do the quest. Good news: The crafted items take up considerably less space in your bank than the components to make them.
