For connection details, you can best check the timetable Annika mentioned. As for validation: depending on where you purchase your pass, you can either validate it yourself (we call this "Quick transfer" in our reseller overviews on each pass page), or you need a stamp from railway personnel. In the latter case, it can be done at a Swiss station or on board of international trains bound for Switzerland. You need to ask the conductor to validate your pass before you reach the first station where free traveling starts; Domodossola in your case.
