First, welcome to forums.

Second, would you share your shard? That means ALOT when it comes to pricing.

Third, here is a link you can use for lake austin. It is an auction house that has sold a few of the items you are asking about. Links are to their sold item price list.
link 1 (HOT auction house) http://mysite.verizon.net/hotauctions/hot_prices.html

Link 2 ICE Auction house

Fourth, check UOAUCTIONS2 prices. Good benchmarks for overall shard value.

Fifth, check SEARCHUO.COM . Login required. This is a searchable database for all Luna Vendors on all major production shards.

Sixth, I have ordered your list in percieve value order, most to least. You were dead on except the jewelry.

1) Full double exceptional Heavy Archer suit of armor, this includes, Chain Tunic and Leggings, Plate Arms and Gloves, Heater Shield and Close Helm. The set is all Double Exceptional Verite armor.
2) Jewelry, 20 Diamond Necklace, 1000 Diamond Necklace, 1000 Diamond Earrings, A Holiday Timepiece (blessed) and 2 Diamond Weddingband

3) Blue Spined Bone Gloves and Helmet.

4) A Happy Valentine’s Day bag (red) with a bottle of Pink Champagne and 3 ?candies? Red “Just 4 U” Yellow “From Me 2 U”, Pink “Hot Lady”

5) Double Exceptional Items, Wooden Chest, Wooden Box and 2 Stools

6) Cloak with Night Sight 38 Charges.

Sorry no exxact prices, but with the subjective pricing going on now, especially by shard, this is the best I can do.
