That first cam might be a problem at the smog station. Since this is a daily driver with some freeway use, you want something that is going to get half way decent gas mileage too. The rear gears are fine for the milder cam and for the use you plan to put it to. You'll want to tap that intake for an EGR valve, or you will flunk the visual and you may not pass the NOX emissions. Verify that the new carb is Ca approved too. Depending on where you are in Ca. the truck may be put on the dyno for a more complete test and not just a minor butt sniff.
