Tickets and Annual Pass Questions - Please add your ticket questions to this thread

I'm debating on getting an AP. A few questions. Since I don't live in Florida, nor own DVC, I only have the Incredi-Pass option. If I have conference tickets, can I upgrade to an AP? I know it's just a certificate until it's activated at WDW. Before activation, am I allowed to book AP room-only discounts? And get other pre-paid discounts like CRT (granddaughter's first trip)? Any gotchas or things I shown be aware of? TIA!
