Re: what's next
Ford Racing C or B springs would give you some drop and aren't overly expensive. You can probably get away with just replacing the springs and none of the other components.
Cut springs would be the cheapest route, but the length of spring is changed while the load is not (not good for your suspensio) and you will wear out your shocks/struts real quick, not to mention the ride would probably be pretty harsh.
