Unfortunately a 29gal does limit your choices. It's the same footprint as a 20gal long, just 6 inches taller so you don't get much horizontal room for territories.
I can't comment on the ram, but Axe the RTS and Gold Gouramis. The former can get very territorially aggressive and the latter are just a plain mean Gouramis. Plus both can get up to 6 inches. Dwarf Gouramis like the powder blue or flame could work
I would say do 5-7 TB's, a few cories, a dwarf Gouramis as a center piece and maybe some golden barbs to add some color.
