Would it be prudent to get the gas port drilled for a rifle length tube given the longer barrel length? Fast cycle rate is not a high priority for my use.

Very good question. Having a longer barrel would be a shame if you weren't going to milk out more in the speed department. The longer barrels, will way more efficiently, use the slower powders too. If you were to put a carbine length port into the 24" barrel, in short order you'd hit the pressure wall and ripped off rims, using the slower powders and trying to increase the speeds. So, my vote would be to go with the Rifle length port, for your 24 incher. Factory stuff will still work pretty good. Even now the rifle length port, works on the raged edge of reliable, with the factory fodder, now add that extra long barrel and you'll have more time for the gases to enter the port and thus the longer barrel would be a little more reliable than a 20" barrel and gas set-up, using factory ammo..t
