And yes, that is correct - all you need to enjoy OS4 style Icons is PeterK's new Icon library.
Please read carefully his documentation for the install, there are some other required libraries IIRC and also you need to install his modified 'Powericons' into C: You also need to have that run from your startup-sequence, he explains this to me is the tread I linked so a good read through that thread will help you for sure.
Good luck with your workbench conversions, you can loose a lot of time working on them as you have to copy 1 Icon at a time
I use a tool called 'CopyIcon' which I have put on the Zone for you.
