I'm not sure what you mean by spec. Bards are primarily pullers and secondarily crowd control. For aa's you can't go wrong with defensive abilities (combat agility and stability). Buy fading memories ASAP and 1 rank of boastful bellow. Also pick up the ones that increase run speed. If you raid, get the ones that increase your song range.
