It's a long time ago now, but I think I had to use two 2555's (one for each employer). As for the 1040, I list the primary occupation for the year. so for example; a surgeon for 11 months and retired for 1, then surgeon would be put on to the 1040. Probably no harm in simply putting Surgeon/Retired.... It's to validate income to job. If you have 100k income and 'House Person' as occupation, then all sorts of flags would raise.
