Just keep your stocking limit in mind, but i think all of the fish you have choose are great.
Also by doing research first (as you are, which i love) you can decide which order to add them. As someone mentioned, by stocking passive to aggressive you should save yourself some from the new fish aggression issue. I would put the cardinals in first, then the jawfish, then the clown.
Also, my cardinal is single and does fine, but they will live happily with other members of their own species. The nice thing about them is, i think, is that you can add them at different time. So you could add a couple of cardinals over a period of a month, which is better for adding your first fish.
The clowns should be added together though! Such grumpy little beasties :)
