whats the gap ment to be for the spark plugs and points
There are no points on a 1990 Pontiac LeMans. You will only have to worry about the spark plug gap. On the radiator core support there is a label listing emissions requirements, routing of vacuum hoses, etc., and this will have the recommended spark plug gap printed on it. If not, a dealer should be able to tell you the gap over the phone.
