You can certainly add the extra components - it's your budget - but series resistors are usually left overs from transistor designs. If you are having an issue with turn on / off times, technically, series resistors will make it worse. They will, however, help improve noise immunity if that's a concern, and it might be with your long runs.
Pull up / down resistors are only useful if you ever tri-state the output. If you always drive either high or low, all they do is waste current in one of those states. They are useful during start-up if there's a risk of damage with an unknown gate state, (say where you could short the supply by having 2 devices on in some designs).
I used to make those same circuit choices (series resistors and pull up/down) automatically, until I sat down and actually did the circuit analysis. In some cases they hurt more than help. (The same is true of liberally sprinkling decoupling capacitors, but I digress)
