Hy there,
imo you should focus on getting a decent DH and upgrading your dagger.
With your budget you really can't afford to split any of it on different things.
Additionally WK is not really needed in PvE as much as DH will be used (besides Mainquest where there are shadow mobs maybe) and in Raids you will not deal damage anyhow, so you are only there for the buffs that can be done in a 20+0 WK.
Best of luck!
