Wouldn't say you're doing too badly, only points I'd make are, you need to choose either Stamina or Haste, don't hybrid gem everything, I see that <Slack> are a 25m, so you might want to consider stacking Stam gems till you're up to a better ilvl and/or have some Stam trinkets to swap in for fights that need them.
Also your trinkets are pretty dire, neither of them are really desirable, and since you're scraping very close to the Expertise cap (which btw, you might want to consider dropping to the soft cap till you've got a bit more to work with) I'd recommend you pick-up a Ghost Iron Dragonling, as for which trinket to have it replace, that's mostly up to you, I'd personally replace the Darkmist to keep the passive Mastery/Expertise, but an argument can be made for either.
Also if you sort your gemming out, you can use the Reds for pure Expertise which should help you out a bit, same for some of the the crappy bonus ones.
Can see you've done your homework anyway, and made the best of what you had, so just keep going
