One copy of invitation letter should do it. For application form, one form but 2 copies. If your father is the main applicant, then your mother is listed as spouse in the same form.

1. Fill one form for each parent, thus 2 in total
2. One invitation letter.
3. If their visit is shorter than 3 months, Med Exam usually is not required.
Hope About help.
