The requirements of broadcast audio can be complex and if the job is done out-of-spec your program will be rejected. If it’s something you’d rather not do, find an audio post house in your area and have them do it. The specs you mention are not legal in my experience. But, broadcast organizations do have different specs, so be sure to find out what they are from the broadcaster you’re working with.
As for other uses, I usually mix the audio hot, but not so hot it clips. You might want to do the same for YouTube.
