so you have a 19 monk/33 shaman and your wife has a 19 pally? i'd probably grind in shrouded isle if i were you, all undead, so good for the pally, and with shaman buffs and pally heals, as well as shaman healing between fights, you should be able to pwn the place's first floor, eventually moving to second floor and roof. you could also put a group together doing it, to grind more efficiently.
in shrouded isle, you especially want the named ghouls (should be doable at your level, roughly) for silvered platemail, and the necromancer mobs inside the mansion. the necro mobs drop fine silk robes fairly commonly, i think like 1.5p each at vendor, and skull staves, like 4-5p? at vendor. also somewhat less commonly you will get items for the wyvernfang armor quest, and some low to mid level gems.
definately where i would go to make cash at your level.
