I like your compilation list, but it's a little too reliant on his Enz material and I'd certainly go for more than just one Swingers track as the album is sheer genius.
Check out his Mr Phudd's Novelty Act which is still available as far as I know and is an exceptional album, there's also a few of his solo tracks as well as some that he recorded with Tim Finn on the Other Enz compilation.
