Other places the engine instruments and general cockpit environement (including at least in a small part the non-verbal comms and body language of the other pilot) are a natural element of constant scanning. Doing the distant stare is frowned upon. PM's responsibility for verification and a callout does not absolve the PF from their duty to know what's going on themselves in the first place.
Depends on variable takeoff circumstances. PF should always glance but in strong gusty crosswind, pouring rain he has the duty to control takeoff run and may be even reject takeoff which PM will not do. So all takeoffs are not same. Once thrust is set let PM do his job. PF should concentrate on what is his priority.
