I love your goals; teaching respect without hurting her spirit.
It can be a bigger challenge when the child is getting different versions of parenting, but she can certainly distinguish at her age that different environments have different requirements.
The single best parenting book I've ever used is How to Talk So Kids Will Listen, and Listen So Kids Will Talk, by Faber and Mazlish. The book is filled with examples of how parents helped estsablished the conditions for the child to address a problem herself. And though we don't usually think about children in these terms, they can be creative problem solvers when given the respect and support to do so.
Plus, kids are more invested in solutions they think of themselves, and are more likely to work at making them a success. I've used these techniques with my grandson since he was around 2.5, and they are brillliant.
