the 6th one down is choose the 'SuJu' image of your choice.
the first radio button is 'select all' and second radio button is 'un-select all'
the check boxes are the names. i guess the names of the boy band members.
they appear like this;
Leeteuk, Han Geng, Kang-in, Sungmin,
Ryeowook, Heechul, Yesung, Shindong,
Siwon, Kyuhyun, Donghae, Eunhyuk,
i don't think you'd need the rest of the options. it's just time settings, and there is a weather feature, but it appears to support korean cities only.
i wouldn't have downloaded this widget if it wasn't from a reputable company though. lucky for you that kyochon is a well known company.
