Is My Gearbox Worn? - Pictures Included

I've taken my gearbox apart for rebuilding, and need to check things out before rebuilding it

Since this is the first gearbox I've rebuilt, and I have no idea what I'm looking for I'm hoping someone can tell me what I should look out for?

ie: What are and aren't acceptable levels of wear, etc....


Now, on with the pictures.......

This is the end of the mainshaft, it looks as those the hardening has worn through to me (but I don't know what I'm talking about so I could be wrong)





Here you can see a small chip out of the first gear





This pictures shows some wear on the teeth, I've pointed out the worst one, but you might be able to see the others have wear too





Another chip, this one is on the reverse/selector hub





Another picture of first gear






And some general/overall pictures




















So, what does everyone think?
Do I need a new first gear and selector hubs?
Is my mainshaft scrap?
I was planning on replacing the baulk rings and circlip on third gear, but I've heard the new ones are awful
What should I do about the input shaft?


Any other thoughts?
