Newly setup 125 is almost 3/4" inch unlevel!

I'd go with the wrasses first. The eel will require you to have a tightly covered tank. They are escape artists (so proceed with caution).

Angel/tang next is fine (depending upon which angel and tang :duh: )
Puffer/trigger last

well im def gettn a imperator, lookng for the smallest adult I can find. And as far as tangs What can hold its own? I would like sohal or achilles but both not practical so not sure, but very fond of them in general, maybe 2 yellows for color
