Your water isn't that hard at all. I've kept chocolate gouramis, which are supposedly even more sensitive to water hardness, in harder water than that. Clean water is the key -- not pH/water hardness -- with fish, unless you are breeding them.
The angelfish should do fine. I would look into cardinal tetras (P. axelrodi) to complement the angelfish. Other good choices and personal favorites include Red Phantom Tetras (M. sweglesi), Black Phantom Tetras (M. megalopterus), and Rummynose Tetras (H. rhodostomus). All of these fish should do fine in your tap water, from personal experience.
You don't need reverse osmosis. And, in fact, you will most likely be dosing some nitrate throughout the course of the week to keep that level above 0 ppm -- the plants use the N as 'food' and will perform poorly if there isn't enough NO3 in the water column.
