Questions on Spiral Knights

Ok,

So im pretty good at figuring games out on my own, but this one I am having some issues with. I don't think i skipped the tutorial, but in case I did i apologize for asking stoopid questions.

• 
  [*]What is the best way to get better gear?
  [*]Is there a way to save your progress in the middle of a arcade thing? (like on depth 3)
  [*]How exactly do you acquire quest?
  [*]And is there anything to do besides the arcade instance format and pvp?

Thanks for reading. Any answers would be greatly appreciated.
