Just bought a 2007 yaris 4d sedan

[le_butters]

As it says I just bought my first yaris. It's a great little vehicle as far as I can tell. I have only test drove it once and my mechanic gave it the approval.
2007 4 door with power everything, abs, cruise control, cd and aux cable, automatic. It has 41800 miles on it. 1 owner before me bought new from from dealer. Clean under the hood and inside the car. Brand new tires and battery put on this year.
So I bring it home on Thursday when I get back from work.
I'm paying 8800 for the vehicle. Is this a fair price?
Also what can I start doing to help improve gas mileage? I've been reading a lot on here already and I guess I'm not seeing what I'm looking for.
My average drive is 84 miles round trip to and from work. mostly highway and interstate. So 65-75 mph most the drive.
Sorry for the long winded post just trying to start figuring out what I should do. Plan on getting a full synthetic oil and good air filter. But beyond that what should I do?

Thank you for the help!
