Default Dual deploy question

I'm a newbie when it comes to dual deploy, but I have a bird (Hyperloc 835) dual deploy ready with all the electronics, etc. I have 2 questions:

(1) I'm using the Aerotech hardware with an H268R motor (not too high, but high enough to test the dual system). Should I just include the delay in the motor build (with no bp charge) or include some kind of cap I need to include to prevent motor thrust up into the rocket resulting in a cato?

(2) I am using shear pins. Two for the nosecone and 3 for the body section for the main. Though I have measured the appropriate amount of black power (about 1.5 grams each) for the respective volumes, should I add a bit more for shear pins?

Thanks!
(Having a hard time finding internet answers for all this...)
