The quest turn-in chest is inside the torso cavity of the statue on the island next to Booty Bay; fly in the arm hole.
You receive all of the listed items when you turn in the quest.
All but the Black Ice can be sent to a bank alt to wear (or sold on the AH, etc.), as the Black Ice is a BOP ring.. but it vendors for 100g if you're not a RPer.
The crown and bracelets are both actually visible without inspection. The Golden Necklace, being sold for just 10.37g AND being invisible without inspection, is probably worth the least to most people.
By quick math, the quest rewards 165g 58s and 87c in items (if you sell it all). The 9g 40s from the quest itself brings the total to 174g 98s 87, or roughly 175g.
EDIT: And the Black Ice IS visible, just not from the dressing room.
