#1 - As a noahide I have heard it being said that it’s alright for us to believe in astrology, and some quoted Rambam. However, don’t you feel it is wrong for us too, since the 7 laws covers idolatry, and one can become so obsessed with astrology and forget G-d is the Director of events?
#2 - If you don't believe that the stars have any independent power at all, that they are simply channels for distributing various influences from Hashem and that an astrology can interpret what influences might be predominant at a particular time, what character traits might be prevalent in a person and what they need to work on spiritually? Is that forbidden? There is certainly a long tradition of Jewish Astrology.
According to most (but not all), authoritative Jewish sources, a non-Jew is allowed to believe in the concept of “partnership.” “Partnership” is a belief that G-d has designated some power to certain entities, such as angels, or stars. However, no one allows any type of worship of these entities that house these imagined powers. All worship must be directed to the One and Only, Omnipresent G-d. But now that you know that this is an allowed, but not factual concept, why bother with it. Why talk to a servant when you can talk to the King?
Not wanting to rely on my own understanding, I asked a very well known rabbi your question regarding interpreting influences that vary from time to time. His answer was, “What is forbidden is to say that this is a good time to go out, or not to go out, to do certain things, or not to do certain things. To say that the times tell me that today is a good day for you to work on a particular characteristic trait is not forbidden. It is just stut (foolishness).
