I'm sorry to hear this.
Airbag light - how long ago did you have the aftermarket radio put in? The accidental airbag light from the radio install would only happen during the install (when someone turns on the key and the passenger airbag off light is unplugged).
Have you had the front crash zone sensor replaced? There was a recall for that for 2005-2009s. (Sticky at the top of the general discussion).
For your blower losing speed 2, make sure the cable connector on the back of the switch is firmly in place. If anything, remove it and plug it in again to be sure. That's where my troubleshooting authority on this ends. Some other members have lost speeds too not sure what they did to correct it. They can chime in on that.
For your fuel guage, unfortunately that has been a more common problem that anyone would like. Theres a few threads on that. search: 'fuel sending' or similar.
I'm pretty sure out trucks don't use the SES light to advise on service intervals. At least mine doesn't.
