HId's Recomendations?

Not that I have a Fusion, but in general Polarion is pretty top of the line, or if you don't want to spend $500 on a kit, XenonExpert carries Xtec kits, which have been decent.

I still don't know what size lights the Fusion uses though.

OK, so same as a lot of the cars I deal with, then (not the Mazda6... Volvo S40 and Mazda3 both use H11's though)

I'm not sure what you mean by your first sentance... but you can check out my recommendations above, for decent places.
