I'm looking for a chart or table or something that describes the fuel
usage
in climbout and descent. I want to know how much fuel to allow for
taxi,
runup, and climbout.

The manual for your engine will include a graph of brake specific fuel
consumption rate as a function of horsepower. Together with the
horsepower dropoff with altitutde factor (sigma - C)/(1-C), using C
about 0.12, sigma is relative air density, you should be able to get a
fairly good approximation to what you want.
