Dps gear would midsummer, solstice and earthstone breastplate and greaves. (This is because they add damage effectively increasing your dps).
Bracelets; Heat, ice and poison are a waste if bracelets. If a venom bracelet had 8 damage then it'll add 8 damage, however if a crush/slash/pierce had 8 damage it'll add around 40-60 damage.
Rings: Here we are looking (this is for offhand blade and knucks) for damage rings. Damage rings will be the fire fang rings ect; these can be obtained for Obby and aggragoth. These are the ones that add 10, 15, 20, 25, 30, 35, 40, 45 and 50 damage. Forget about royal and grand rings if you want to short distance dps.
Personally i use 3 damage rings and a grand light heal ring, light heal can come in handy for when a boss has cloak or when the tank needs a support heal.
Converting from normal frozen or meteoric gear and quiver to offhand blade an knucks is expensive. Just save up, dont swap your bow and quiver because you might not like the new style:)
Here's a total price, blade and knucks = 321k, dont forget this is your basis. You need a damage helm 150k which totals to 471k. Heroic gloves adding an additional 150k suming up to 621k.
621k is the basis of how much it'll cost (excluding the prices for dps gear, it varies on different servers).

hope this helps:)
