Now I know reducing rotational weight will help improve speed and climbing but does the same increase on climbs decrease the speed on my descending because theirs less weight going down the hill?
Only actual weight affects climbing and descending. So getting wheels that are 500 gm lighter is the same as reducing some other component by 500 gm. Rotational weight affects acceleration/deceleration. Lighter wheels accelerate a little faster and but lose speed faster, so you might surge and lag compared to heavier wheels which tend to even out your speed a bit, but the overall speed comes out the same.
