You can do this to change the next value of an autoincrement column:

ALTER TABLE tablename AUTO_INCREMENT=X

Also, do do this:
subscriptionsubid ------------ < --- ("2" IF above field mc_gross is 4, "1" IF above field mc_gross is 6, "0" IF above field mc_gross is 10)

I would probably end up running 3 different queries based on the number in the mc_gross field. Would I be able to create a query that says "Only run IF that field value is x?

You could use CASE:

CASE mc_gross WHEN 4 THEN 2 WHEN 6 THEN 1 ELSE 0 END

I think that can be used in place of mc_gross when listing columns in a SELECT.
