Can't answer all your questions, but I hope on the sleep / cuddling / emotional needs, you'll keep in mind that all babies are different. And that most babies' sleep patterns change frequently as they grow into toddlerhood. We don't get to choose what our little bundle of cuteness brings along with them in terms of their emotional needs, we just sign on for mommying to the very best of our ability for however long it takes.
Our Western expectations that we will live in houses with separate rooms for the little ones is a fairly recent development in human history, and is actually considered strange by some other cultures where babies are kept close to their moms or other caregivers more or less constantly.
You'll probably only get "your space" back when your daughter's emotional and physical hunger for closeness has been satisfied. You can force the issue, but there's too much modern research that shows kids who have to give up that nurturing before they are ready suffer for it with health and mental issues to a much greater degree than children whose needs are indulged.
Your daughter will crave separation and independence when she's ready for it. Once that time arrives, you'll be amazed at how quickly these early years have passed. Until then, I hope you'll learn how to cherish the closeness she wants to have with you.
