Hi John,
Congratulations on joining the ranks and it is great to see you will be trying for Expert Infantry and hopefully Centurion.
With respect to the helmet, as Glen mentioned, the Level 3 CRL states “Ideally, placement of ears (and screws) should closely follow the rear angle of the trap above them”
As this is a Level 3 (centurion) requirement, it would not affect your EIB application at all. As the CRL states "Ideally", we do not reject applications if they are not perfectly aligned and therefore it will not affect EIB or centurion approval

For the thermal detonator, Ideally the screws should be a bit smaller and not as close to the edge of the clip as they are but I would say that it would still pass based on the CRL description.
