I have 2 questions for all you AP experts, hope you can help me out

.
1. I have a trip coming up in June (arriving very late 6/10). My AP expires 6/7 and I'm planning to renew. If I buy a multi-day park ticket now and link it to my account, can I put the cost of the multi-day ticket toward my AP renewal when I arrive in June? I was originally planning to renew after I got to Disney as I would be within the 30 day renewal time frame; however, I realized if I did that, I wouldn't be able to make FPs at the 60 day mark. I can pay for the renewal now, I was just trying to spread the cost out a little if I can (hence the reason I'm thinking of buying a multi-day ticket now and renewing/paying the difference in June).
2. I have 1 night RO at CBR (6/10) before moving to YC CL on 6/11 (also RO), both of which are booked under AP discounts. If the ticket purchase/renewal mentioned above is doable, are my reservations ok even though my AP wouldn't be renewed until the 11th? Or would I be taking a chance that I'd lose the AP discount on one or both reservations?
I know I could ask this question on the theme park/ticket forum, but several posters here are very knowledgeable and helpful! TIA for any information you can give me
