I think she'll be fine. The more often you work with her, the more fit she'll become, so she'll sweat about the same, but she'll seem less tired.
As long as she's cooled down properly and not just thrown back into her stall sweaty with no blanket, she should not get sick. She could have been coughing because of the dry air (Like people, horses get runny noses when it gets cold. If the snot is green or yellow, then she is sick. Otherwise its nothing).
An hour of w/t/c is nothing. I'm sure she'd be fine if you rode her on the days that your RB did not come out, and if you want to ride even after your RB, you could probably do that too. She's young, she can handle a little bit more work than an older horse would be able to.
