hi, I try to answer your first question :)
1. You can see that the (1-k) outside the integration is for the case of small frequency error( (1-k) --> 1) . As to (1-k) inside the integration, I think it is to put the integration 'sleep' when frequency error is large. Note the integration with reset, which means once the phase exceeds 2*pi, the integration will reset. This reset could be useless for the large frequency errors( (1-k) --> 0 ), because in this case we consider only the k*H part, not the integration part. So (1-k) is put into the integration to make the reset happen non-frequently. At the same time it has no effect for small frequency error, as (1-k) --> 1.
