Nightwalkers: What to buy ahead?

Well, considering I am going to make a nighwalker before my dawn warrior, I want to buy some things ahead of time for my nightwalker. Thing is, I don't know pomegranate about gear for sins/NWs. What are some regular things I should buy ahead of time? (We are talking regular equips here, not OMG DAMAGE WHORE equips)

Maple claw, kandayo, so that you don't HAVE to get booster as soon as possible.
Other than that, just buy 1 set of good stars (tobi if you're poor, ilbi+ if you have decent money) after you max vampire and crit, because that's pretty much all you need til 100 (vampire doesn't use stars, and poison sling in 3rd doesn't use stars).
