I understand when to use the qui/que part and have no problem. I cannot wrap my brain around when to use ce qui instead of qui and ce que instead of que can someone explain?

In the sentence 

Je savais de plus en plus ce que je voulais

Can't it be que instead of ce que

And since ce que is what which means noun why we used de plus en plus and why imparfait is used not passé composé? Also if there is a verb before the blank and a noun after what would we use de plus en plus or de plus en plus de ? If nothing is after then?

In the lesson it states:

"When last time is followed by a clause (last time I saw you), you can only use la dernière fois, and never la fois dernière." 

but there is a question that asks "_______,  Henri est venu me voir." ("Last time, Henri came to see me") One would assume the answer would be "La dernière fois," but that was not listed as an option for multiple choice.

Instead, it says that the answer is "La fois dernière" (the other multiple choice answers are: Dernière fois/ Fois dernière/ Une dernière fois). Is this because there is a comma, so "Henri came to see me" does not count as a clause following "Last time,"?

If these phrases have the same meaning, as noted in the lesson, why was answer deemed incorrect?
