I went to the USGS location site (FABULOUS for finding almost anything):
http://mapping.usgs.gov/www/gnis/gnisform.html
and after poking around and accessing a map, it seemed that Graceland might be closer to West Superior than Superior itself. Not that it matters much -- it's all within the same area, really. If you want more info on the cemetery itself or the address, call Down's Funeral Home 715-394-7746, or one of the other funeral homes in Superior. They might also know who holds the records for the cemetery. If you want to find newspaper obituaries for deaths in Superior, call the Area Research Center at the Superior Public Library. They have an obituary index there. Good luck!
