Changing to 18" fronts?
What does it do to the geometry of the car if you go from 17s to 18s on the front?
It will raise the front .5" but does that affect the handling? Do you compensate by lowering the nose .5 or lower profile tire?

then buy bigger wheels and tires for the rear. 18s or maybe 19s ?

I'm running 19" fronts, and the tire height is identical to those of the stock 17's.

As long as you keep the same proportions in tire sizes, you'll be fine. Otherwises, you might have active handling and traction control problems.
I'm running 265/35/18s in the front and 295/35/18s in the back using 18x9.5/18x10.5 high polished Y2k wheels.

Do not do this, it causes major problems with the Traction Control.
265/35/18 and 295/35/18 are correct sizes.
I don't know about better handling but 18s up front look very nice, the back could use 19s in my opinion
