Runewords (Arreat Summit)
For Rhyme you need only Shael and Eth runes, Shael can be dropped by NM countess - a quest superunique monster in act 1 in Forgotten Tower. She is known for high chance to drop medium runes.
Good weapon is the one with high damage and fast (naturally fast + with IAS). Werewolves are good with 2h weapons, one of the best cheap weapon for werewolf is acually unique XBow Buriza do Kyanon (which can be traded for Pgems I think). They can do well onehanded too, but Aldur's Rhythm is quite slow and with low damage. What rune did you get from NM hellforge? Maybe you can make Black runeword or something. If you don't trade, you pretty much depend on your own. Well do few Mephisto runs, maybe Baal runs, see of something good doesn't drop. In my experience, it's good to level your character to lvl ~80 before you advance to hell, so defintily do Baal runs until you get to that point.
Well your belt has only +60 life, you can shop for one with at least resist+life. On rings and amulets, look for resists, AR, leech, life, +DEX, +STR. +skills are nice, but not so important for werewolf.
Werewolf is quite a good build, it's the gear that need serious work now. (Melee builds are more dpendant on the gear, you can't do much about that)
Maybe read some Werewolf guides in druid forum. And take a look at werewolf weapon speed calculator (should be linked from every decent guide).
EDIT: The good accessible weapo for you might be an Insight runeword. Slow, but if inserted in elite polearm, you will get a lot of damage.
