method.params.each do |param|
  if param.default
    puts "#{param.name} (= #{param.default})"

param1 = method.params[0]
puts param1.name # => Filename
ole_type

Returns OLE type of WIN32OLE_PARAM object(parameter of OLE method). 

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')

param1 = method.params[0]
puts param1.ole_type # => VARIANT
ole_type_detail

Returns detail information of type of argument. 

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'IWorksheetFunction')

p param1.ole_type_detail # => ["PTR", "USERDEFINED", "Range"]
optional?

Returns true if argument is optional. 

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
