You were so close. When writing to a property of an object with perl, you have to enclose the property name with {}.

# $ins_range->Font->Name = "Arial" gives illegal lvalue
# turns into
$ins_range->Font->{Name} = "Arial";

Since you're using OLE, you'll be working with objects a lot. Always remember that properties are enclosed in curly braces.

As for your other problem, without knowing what you are trying to saveas, I really can't help you out.

P.S. msdn.microsoft.com is the best place to find information on the OLE interface. If you want the examples in perl, just change all the '.'s to '->', put '{}' around the properties, change 'Dim' to 'my', and add a '$' in front of the variables ;^)
