I was gonna do the whole sea foam thing to the tundy but i thought it was too new for it still, besides i've only filled with base gas a few times. For the CEL, its normal for it to turn on, when I add sea foam to my celica it usually comes on, since ur adding liquid where normally air goes in. For the other things turning on, I would suggest unplugging your battery to reset them.. if you want to improve your gas mileage i would recommend Zmax, I've added it on my celica, and it actually improved the gas mileage on it. Hope this helps you out a lil.
