Can anybody suggest a good way to:
1) Given an ordered set of objects, create a new non-mutable ordered

with all the duplicates removed?
You could do this using the KVC set and array operators (http://developer.apple.com/documentation/Cocoa/Conceptual/KeyValueCoding/Concepts/ArrayOperators.html
):
NSArray *arr = [NSArray arrayWithObjects:@"A", @"A", @"B", @"B", @"C",
nil];
NSArray *arr2 = [arr valueForKeyPath:@"@distinctUnionOfObjects.self"];
