Hi Bob! It sounds as if you've made excellent strides in the two short months you've had your girl. Since everything is going well, I wouldn't change a thing just yet.
Generally, up until a full year of age, we consider puppies to still be puppies, and therefore not 100% reliably house trained. She may still have an accident at night and she is used to her crate. The crate is her safe place, where she feels totally comfortable. In there, she knows it is bedtime and sleep time.
However, there are no hard and fast rules! My Cavaliers have slept in a bed with either me, and/or one of my sons, since they were 4 months old. If you think that your dog is ready for all night in your bed, then give it a whirl. You will know quickly enough if this is a good idea. If you find on the first try that it doesn't go successfully, go back to the familiar routine for a few more weeks, or even months, and then try again. Some dogs never adjust or like sleeping in our bed, and others take to it like a duck to water.
Remember that you want to continue this successful house training more than you want her in your bed. Since she is doing so well during the daytime, I too would take the reduction in walks slowly as well. You've only had her for 2 months which isn't very long.
Clearly you have good instincts, so continue to follow them, and kudos to you for adopting.
