Supposedly the transmission has a cooler that pumps oil somewhere up front for cooling.
The Ultramatic transmission pumps fluid to an oil cooler up front.

It seems like it would probably be a good thing to replace any hoses involved since they are probably very old.
The lines to the stock trans cooler are 100% steel tubing; hence, no hoses to replace (no need for them). However, if somone has ADDED a cooler (typically, in front of the radiator), there will be hoses somewhere between the powertrain and cooler, to permit flexing under load.

In pulling the radiator, do oil lines have to be disconnected? Any tricks on this?
If you look under the hood of your car, at the back of radiator, you should see that there is no oil cooler in the radiator; hence, no lines to disconnect.

I can't seem to find this in the manuals.
Take another look at the service manual, specifically the section on "Radiator & Cooling". On page 3 of that section, Figure 6 shows a bit of the trans cooler - pointed out by lettered arrow, described in the text. The cooler can also be seen, in profile, in Plate 27 of the parts book illustrations.
