Just to give you better item lvls, and not taking into account which pieces actually provide upgrades...
245 Helm and Shoulders from Triumph Emblems
232 Tanking Weapon out of HHoR or HPoS
232 Tanking Neck out of HHoR
226 Belt From Emblems of Conquest
219 Cloak out of Regular HoR
219 Shield out of Regular HoR
Those should get you well above 5k. Also if you get rid of some of your defense enchants/gems for more stamina you could pick up the 245 Armor Trinket to Replace Essence of Goss while actually increasing your hps/eh. The 232 Weapon and Neck are the only two you will be limited on attempts for in a day everything else is a regular instance or badge farming. Best of Luck.
