For most of your questions answer is Yes.
Robot integrator should pay attention to robot,its environment, safety and so on...
I will share piece of advise:
Don't underestimate influence of technology on difficulty level of robot integration. Even simple pick and place or palletisation can became nightmare if you ignore role of mechanics and basic physics. For example 20kg bag of charcoal and 20 kg bag of sugar, are different tasks.
Always double check fixing robot to the ground. 2mm backlash with 2m long robot arm ends with at least 2 cm of missed position.
