That reddit guide is pretty good. I'd also add to run the daily story and low level every day if you can, they are pretty easy and fast, and will kit you out in darklight pretty fast. Especially if you don't feel comfortable in the high level dungeons. That will get you to run Crystal Tower, which isn't really that hard if you can learn what to do when, and aren't in a derp group. One drop a week, but a ilevel 80 item, which is pretty sweet.
