Should I worry about the carb or just drain it and shoot it with carb cleaner?

If you have to pump pedal to get a firm feel, you have a leak.

"Seems if I pump the brakes they get firm at a higher pedal height. If I'm cruising the first time I hit the brakes they go down a bit further."
This is a very common problem with 521 trucks. The wheel cylinders have only one port for fluid and air to go in and out of. You have to allow the brake shoes, and springs to collapse the wheel cylinders, and push any air in the cylinder back out to the bleeder valve. If you use a pressure or a vacuum bleeder, the exchange of fluid for air never happens in the wheel cylinders.
Bleed the brakes manually, with two people. The person under the truck has to open the bleeder, when the brakes are applied, and the pedal has to go all the way to the floor, and held there. With the pedal on the floor, the person under the truck has to wait until all fluid (and air) flow stops. Then close the bleeder. Then the pedal can be let up, slowly, and pushed again. Three full pumps, and refill the master cylinder.
