wellllll... a 71 warrior most likely can not solo anything at level 71 that would result in a weapon you would want to wield. however, if you have a group, you could do some Dragons of Norrath tasks, collect radiant crystals, and buy some upgrades from the merchants.
alternatively you could do select Depths of Darkhollow missions/tasks, some of them result in nice drops for a lvl 70, both armor and weapon.
you know, offhand i can't think of any quests that result in weapons for a player of your level. as for armor, you could supposedly get your blacksmithing up to 300 and craft cultural armor, provided you were willing to spend hours upon hours at it. ..
otherwise.. if you're willing to wield a lvl 50 or 60 weapon, you could always log onto a normal server, run a character to the bazaar, and over the course of a few days just search for armor and weapons that fit your class on Test, and then cross-reference them on allakhazam, find out where they drop, and camp them.
