I see that toolrage has found the Allakhazam forums...
Typically (as I believe several of us on another forum have tried to tell you before), your server's bazaar is a better spot to make a deal... While not impossible, or even rare, to find someone that's on your server here that can make you a deal, you'd be much better off in your bazaar.
'Course, it'd be hard to know who can make you a deal if you don't let anyone know what server you're on... Also the servers are down atm, heh... *accepts Captain Obvious award*
As for the earrings, there aren't many options for a level 22... I'd say go with two Orc Fang Earrings. Those lasted my rogue to his upper 50s.
And about the Platinum Fire Wedding rings... Offhand I'm thinking 200pp-ish for them... Of course prices vary by server and random chance, but I think that's the general range of it, assuming my memory hasn't completely failed me.
