No and no.Farland said:So, if a sorceror has burned all his 3rd level spells but has 4th level slots open, could he maximize a lightning bolt, or would doing so require a 5th level slot?

Maximize is a +3 metamagic. You'd require a 6th level slot. Answering the question I think you're trying to ask, all you need is the 6th level slot. Even if you've used all your 3rd level slots, you could still cast a maximized lightening bolt (assuming you had a 6th level slot left).
