Hello Christian,

That's a good frame, as most 45s frames still are.

Yes, the reel should be straightened and painted first.
But remember, NO powder coating. Conventional painting is the best.

I can't personally recommend a sharpening service in Melbourne.
I know ADE use Foley grinders at Cheltenham.

Administrator Deejay is the star of the videos.
Hopefully, now that he's back, he will want to say something here.

As to the 3/4 clutch inner half, I'll leave that to member Bonnar Bloke.

Hope this helps.
