Blackfeather Roost in the TSS expansion would be great at your level, specially with either a tank or healer merc. (Tank? well, yeah, if your skills/DPS are out of practice, the tank will mow through them.)
Get the AA's you want at your current level, then level up. The way the bonus XP works for mobs near your level, it will go quicker that way.
