I would also suggest, while the TSO instance gear is nice and some shard armor will pad your gear until the bigger raid drops ( or higher end instance gear, which ever flavor you prefer) to hit up some of the kunark dungeons along the way. Some of the items are still pretty high on the list of want to have items. Praetors Guards from VoES, the ring from Agony etc. And its decent AA. I always like to take shots at that stuff while you gain the most from it in terms of exp and AA.... though I still haven't gotten my guard....stingey ass phylactory.
Sadly its getting a bit harder to get groups to roll em, but if you have a solid group of friends or guildies that you run with. Just hit up the 80s that are AA hunting how good mentoring is for their AA.../nod
