Good beginner run but for sure the ante is up a little at these flows. There are what are rated as class III- rapids on the stretch. As mentioned, Cottonwood will have big waves and a hole at the bottom that should be missed. Before Cottonwood is Tincup which is a good drop with some big tail waves. Jeeze, I can't remember, is Badger Creek above or below Rincon? If it's below it's pretty simple, stay left away from the big rock pourover, otherwise it's just waves. There are some smaller rapids that at higher flows will have hole and rock dodging with strong eddies. There's one called (I thinkn) red rock or coal creek that at high water has some small holes that could trip up a beginner.
All and all though, I'd say it's a great beginner stretch though, swims should be easy, lot's of eddies to practice on, good mild play spots and no bumper to bumper raft traffic.
