Welcome. Yes, there is piles of info here.

As far as your TPMS light goes, I fixed mine with a little piece off flat black electrical tape cut and put over that stupid light and outdated system. There are other ways to shut it off permanently. Some will scoff at my fix but I guess I come from a day when I learned to look at my tires before I get in and drive and never needed something to tell me a tire was low... Just as I never needed stickers placed here and there about oil changes or a reminder on the dash telling me it needed changed. Ya can spend lotsa $ and maybe get that TPMS monitoring system up and working again like stock but really? Why even bother? It's an old system that signals whenever it senses a tire is more than this or that percentage different from another tire... it doesn't tell you which one! Just an old crap system.

#1 things I know... Have a spare working RCM and crank and cam shaft position sensors. Go under the back of the car and push up and out inner-most rear trunk-well plugs on the left and right before water builds in them and eventually destroys the module in the passenger side rear (that is crazy $ to fix). And do the "sticky key fix" as it is not a matter of if but when that problem will present. Check the inside of the little door to the interior fuse panel on the driver's side and see if "Sticky Key" has been written there as that is where many will write that it has been done. If it hasn't been done just drive the car and at the first sign your key starts to get sticky trying to start, shut down, or remove... That's when you do it and do not delay doing it.
