Will 18x9 fit on the front?

If things like emissions, efficiency and streetablity are of no concern, 300BHP should not be a huge undertaking for a 3.2, nor insanely expensive.

Regardless if it's WHP or BHP, that's way too much unsprung rotational mass to effectively improve performance on any level.

OK, so I need to go smaller - how about 265/35 on front and 295/30 in rear?

I don't have much experience when it comes to race/track applications. However, based on the size(s) of the wheels alone, one would have to think that you're adding a tremendous amount of unnecessary weight. Especially, considering the fact that it's unsprung rotational mass.
