Regarding the weapon: this is a bit harder. Your easiest shot will probably be
Marrowstrike from Trial of the Champion, heroic mode. Additions to that are
Orca-Hunter's Harpoon from HoS heroic mode, probably better but harder to obtain,
Tower of the Mouldering Corpse from Forge of Souls heroic mode, same-level, better itemized, (imo) a bit less easy to farm, and
Staff of Feral Furies form the Argent Tournament, either by doing the quests, or by farming Champion's Seals inside Heroic Trial of the Champion. Less stamina, but nice armor addition.
A sub-par alternative is
Staff of Trickery from Violet Hold, heroic mode.
If you can afford the gold, then
Battered Hilt becomes your target, giving out
Lightborn Spire at the end of its questline. By miles the best weapon you can get your hands on before entering Icecrown Citadel, and even that it's a good shot until you meet weapons with 264 item-level. The Hilt goes from around 7000 up to over 15000 gold, depending on the server, so it *is* pretty damn expensive. The alternative is farming the Icecrown three heroic dungeons until one drops and you win it. Good luck, we all know the pain.
