I would replace the fork, though it could be difficult to find a nice enough canti'ed (non-unicrown) one, depending on the selection at your local co-op. Then look around for a shade of white paint that matches pretty close. The color can be off a little and it won't be noticeable. Save those "Tange" stickers by steaming them off or using a hair dryer to carefully remove, and put them on the new fork.

I think the frame is probably fine. It may have been stressed momentarily, but not stressed enough to actually bend (i.e., it withstood the stress successfully) so unless there's something I'm not seeing in those photos, I think you're fine, frame-wise.
