is there any way on turning thie quest in past honnored with the faction i still got aobut 400 of them that i was hoping to turn them in
Nope. Once you get into Honored, the quest stops being available. You could always save them for any alts that you plan to send through Zangarmarsh.
Yep, they're just alt fodder now. If you're not doing alts, they sometimes sell well on the AH, though your chances are better later in an expansion, when people tend to be working on alts more.
