Update time:
First, I decided to ditch my plant-less tank idea and ordered some easy to grow plants. Several different species of anubias, some water sprite, water wisteria, and Java ferns. Tempatures here are frigid, so I'm guessing the plants will not be shipped this week. I'm perfectly fine with that, it would stink to get a box of frozen plants.
Secondly, all the rescue fish are doing great! I'm honestly very surprised, I figured there would be at least a few casualties, especially the tetras which looked horrible when I first added them.
I've been looking into angels and some of the koi varieties have really interested me, gorgeous fish! I was hoping my LFS would have some of the koi variety but they only had the normal brown/grey banded ones. I'm beginning to think I'm going to do Angels in this tank, they just seem much less fragile than discus.
I'll post some pics once I recieve the plants and get them all positioned in the tank.
