Has anyone switched their 16's for 17's and had much problems with their odometer or gas mileage?

Switching wheels alone should have no effect on the odo/speedo. No changes there mean no MPG changes. There are 17" tires that have the same circumference as the 16's you have now and that is what needs to be maintained. The GT' have 225/50/17's, probably the size tire you need.
