Glad to see you finally got your truck!!

There is two common reasons for a front area squeak;

#1) The rubber pads located on each side of the fenders supporting the hood can become dry and dirty, causing a squeak.

#2) The swaybar bushings that were offered.

The rattle could be one of the most common reasons, which is the rear seat backs. Fold them down and see if it goes away. If it does an easy way to fix it is to recline them just by 1 notch or more. For some reason, if they are in the full upright position, they can rattle.

See if that works...

Good luck with your new baby!!
