Is there some generic resistor wattage to use, for when a circuit doesn't specify it?
I've pretty much settled on the TL783 as doing what I need to do.

Figure 19, page 10 looks like a 6 amp regulator circuit:
(For my case the input would be bridge-rectified AC, and the 3.3 kOhm changed to 8.2 kOhm for 125v DC output. An AC line isolation transformer will be used on the input side.)
I can read schematics, but this app note leaves out some important details, such as the wattage rating of all but one resistor.
Can I just assume 1/2 watt is fine if the schematic doesn't specify it and there's no general value listed elsewhere in the application note?
