[Closed] New frame arriving soon, very excited but need a few parts to complete

So I've got an intense tracer 2 coming in a few weeks and need to ensure I've got all the bits to complete it.

I'm using all the bits from another frame but some parts are going to be the wrong size.

So need:

A new headset as the tracer 2 is full 1.5
Seat post shim from 30.9 to 31.6 so I can use my old post
Need to convert my pro 2 to for the 12x142 rear end
Direct mount front mech.

That's it as far as I know. Anything else that I might need?
All my bits are coming from a Chameleon.

Can anyone confirm what is needed to convert my pro 2 to a 12x142?
