Is a 35/45 the same as 45/35 or does it matter which way is internal/external.

Doesn’t matter. So long as the 45 and 35 go the right way round. Only exception is when you buy a high security barrel. The external measurement is the high security end and will be marked as Ext. This is the outdoor end of the barrel. The indoor end will not be marked.

I bought this product and my keys arrived with a 6 number sticker attached to them, I was wondering what these numbers mean?

If you need spare keys that is the number you can use to get replacement or alternatively forget it and just make sure you do not lose them all.

Can I fit this to an internal wooden door with 35mm thickness?

Hello, this type of lock is designed to fit an external PVC door. It will not fit a wooden door, you will need a more traditional lock. Hope this helps

what profile keyway do these have?

To be honest it will depend on which manufacturer you purchase from.sorry if that's NO help
