If the old hub is in good shape, then it likely could last a good long time with new bearings and possibly new cones.
What brand of hub are you using? Freewheel or Cassette?
I'd go ahead and source good name brand spokes though. DT, Sapim, or a few other brands (get spokes after you decide what to do with the hub).
And if you do need a new hub, what type of brakes are you using? Number of speeds on rear?
