It would be a really good idea to lvl whm up to 37 at lest so you can sub it with any job (or job lvl) and not be gimp'd ...

Bard rocks, its a great enhancing type job and i bet you'll be able to lvl it fast ... that is if you have the gil and don't have to farm too much.

But better safe than sorry i always say ... and from what i understand in a PT POV Whm is like the best sub for brd. At least til you reatch higher lvl's.
