I don't know about all you ask, but the 'c' partition should always
be there and be set to identify the whole slice eg start at 0 and
the size be the size of the slice.   The system uses it to identify
some internal information about the slice.    

Sysinstall should handle that correctly just fine.   
I don't know why you do not get ad0s1a, swap, ad0s1d, etc.
Maybe, if you deleted that special 'c'  partition, it made
the rest of the process screw up.
