I don't like bala. They get big and they're skittish. Which means eventually they spaz out and smash into the glass and die. You seem to have a higher budget than I do so I recommend you look into Denison Barb(Puntius denisonii) as a substitute. They have them at the Shark Aquarium and they're gorgous.
For you because of what you seem to like I'd say start off with a couple of dwarf gourami. A pair of regular or blue dwarf and a pair of honey dwarf. Then add the angels.
German Blue Rams are difficult to keep, but in a planted tank with angels... wow.
