you must take it to a good lbs and have it checked over thoroughly for structural damage; if there's a crack that you haven't been able to detect the fork could suddenly fail under you, which you don't want to happen at all.

assuming you're talking about a mercier kilo tt, it's steel and threaded. if it's a minor misalignment then steel can certainly be "cold-set" (ie bent) back into shape, by someone who knows what they're doing. if you're thinking to replace the fork you can do so with either a threaded or a threadless one, as long as it has the same size steerer (1", i believe), however to run the threadless fork you'd need to replace the headset and stem too, as the ones you have are not compatible
