Ankh Shield - Terraria Wiki
Balloon/boots can be replaced by Wings, you don't need all three, especially if you have higher end wings (you want spooky wings eventually)
Lava Waders aren't very useful end game.
Why aren't you wearing a wall of flesh item? You can get these now: Warrior Emblem - Terraria Wiki Avenger Emblem - Terraria Wiki
And later upgrade it into: Destroyer Emblem - Terraria Wiki
(You can actually wear all three if you want to stack damage)
Get those reforged to all to +3 or +4 armor and that should pretty much get you through hardmode dungeon.
