The setup issue with 5.4.1 has been fixed with HUD v5.4.2, out now at the Update Switch.

If you have cuffs v2.2.3 and gags v4.0.0, just choose “HUD only” during update and transfer your existing gear over without setting up a thing. If only one set is outdated, choose “HUD + gear” for the set that is outdated, and after setup you can transfer the other set over.

[edit] Oh, don’t forget to use the latest ZHAO included with the cuffs (thanks to Annmarie Coronet for working round an SL bug that kills a Priority-3 anim when you bump into something).
