Thorin's Hall reputation-restricted area has a nice feel to it.
The first quest hub inside Great River is quite lovely.
after Trollshaws you will have more or less outlvld most of Evendim (sadly, it's a lovely place).
I suggest doing every bit of epic you may have left if any and head off to Angmar (start questlvl 40, can take them 5 lvls earlier)
After Angmar it's Eregion (start level 48, can take them 5 lvls earlier)
-poke people about info on where to go for your Legendary Items around lvl 45-48
will make a smooth transition into Moria with start quests level 51 at Treshold I think, as always can take any quest 5 lvls ahead but they begin to be tougher here and if you finished Eregion, you will be perhaps 52 53
