Since Resolve is up all the time once it's stacked (and it stacks fast), you should treat it as a permanent dodge buff. So, when balancing dodge and parry, keep your parry close to your dodge with Resolve stacked.
You want to balance these things WITH buffs as the idea is to be CTC with raid buffs - food/flasks/buffs included. This will generally only be Kings, Horn, and Lavascale Minestrone. You want your dodge/parry to be equal at that point.
When balancing it without these buffs (When I used to do it, I knew that 100.45% unbuffed = CTC raid buffed for my gear but it varies per person) you want your dodge to be 200 rating higher than parry because then with raid buffs they become equal as parry increases with raid buffs but dodge does not.
