I understand that you may have already of gotten your fish, but I'll toss in my two cents. \
Personally, I wouldn't go with the Gouramis - they can tend to be bullys and fin nippers and your tetras might fall under their wrath. My own experience found a single Gourami began picking on his companion Gourami. After removing that Gourami he began picking on ALL the other fish. Finally we had to rehome him...
With a final stocking of...
5 Harlequin Rasbora
5 Black Phantom Tetra
5 Bronze Cory
2 Honey Gouramis
Should be fine, I would slightly over filter. Definitely have live plants, and stick to your water change routine.
Dwarf Gouramis as a rule ARE very agressive.
However Honey Gouramis and Dwarf Gouramis are two different species. And honeys generally speaking are very peaceful, and do well in a m/f pair.
