Best autorotation speed is 80-100kts. ARA`s are done >80kts.
With regard to the first, I don't think one more yellow caution would really be a distraction when you HAVE to do an auto!
With regard to the second - if that's your Company's SOPs then you should be directing this point to them. There is no reason I can think of why you would want to complete an ARA at a speed greater than 80kts???
