Service Resource Planning on campaign's target groups?

Hi Experts

I am creating a activity as follow-up doc for opportunity associated with a account. During activity creation, i  have to assign  employee to activity based on employee's  availability and based on employee's location. To get the employee availability and location, I may need to depend on HCM.

Here is CRM Service Resource Planning satisfy the need to assign employees to activities?

How to implementSap CRM Service Resource Planning firs time?

Is it possible  to utilize Service Resource Planning  on campaign's target groups?

What are the integration steps between HCM and CRM to get the employee location and availability?
