None of the ones your missing, biggest thing I would suggest on training to make it worth more is Dungeoneering. Once it's at 85, this account is worth $70-90.
I would suggest you separate the bank from the account, in this way, you can minimize the time to sell it, the bank itself is worth around $300 and the account is around $50. The reason why people buy accounts is for the stats, not the bank, i suggest you sell the bank separately.
