Offer a Free product and a one time discount for subscription purchase

Scenario

I want to offer my subscription product at a 40% discount applicable only for the first order for customers who are not Active Subscribers and offer a free add-on on their purchase.

Let's give these names to keep things simple

1. Product A = Subscription product

2. Product B = Addon product

Limitations that we'd want

1. The discount should only be applied on the item (Product A) when purchased as a subscription by a Non-active subscriber.

2. Customer should not be able to avail the % off discount on bulk orders, ie - the discount should only be applied (to ProductA) if the customer purchases less than 5 qty of the product

3. Only one subscription line item should get the 40% off.

4. Only one qty of Addon product should be offered for free, extra qty should be charged.

How do I set this up?
