The dep Star will hold you over until you can get a Mark of Naricain or Horntail Necklace. The Skanda should do just fine until you're ready to start getting late-game gears together. Personally, I would not get attack work gloves. Wait until level 80 and get some level 80 thief gloves then scroll for attack. You'd do better to hold off a few levels and go for the Hwabi. They hold more per stack and are cheaper. If by "level 17 rings" you mean Evolving Rings then, yes, they are worth it. It's hard to pass up 7stat/5att rings. Also, you might just hold off on the zhelm too. At level 80 you'll be able to use a Scarlion or Targa Hat, which are much better.
There really are a lot of options when it comes to accessories. You'll want to look for getting the most +Dex on your stuff as possible. This way, you won't have to put as many points into Dex to get enough for your claw.
