A normal OE spoiler will not affect the mileage by any means. A GT spoiler MAY have some effects on the aerodynamics and stuff , not sure though.
Yes 15 inchers cause some suspension problems in the longer run and the ride will be a little more harsh. Better stick with 14 inchers and 195 section tyres.
Driving constantly around 80kmph in the fifth gear gives the best possible mileage for any car in highways. Very much possible , but we people atleast me never can drive constantly at 80kmph.
