I am very new to PalmOS programming and can answer only some of your questions - and because I've hit them too recently. :-)

What kind of icon > (family, size, density) should I create to display it in the List > view? Ah! There is a little trick here. :-) It is indeed the small app icon that is displayed in list view - and which particular one from the family is displayed depends on the properties of the display. That is, PalmOS automatically selects the "best" icon - i.e., the one with the most colors or shades of gray - from the family that the display of the device can handle. However, the IDs of the icons do matter. The large app icon must have ID 1000 - which is usually the case. But the small app icon must have the next ID in the same family - i.e., 1001. Yours is probably 1100 or something like that - that's why it is not displayed in list view. Change the ID of the small app icon to 1001 and it will be displayed.
