Nice. The Rams and Angels, being cichlids, are the only ones I would have been worried about, but since you plan to (or hope to) place them into different tanks when they mature, it's fine. The GBR's will end up with a pair and a loner, take the pair out and leave the loner behind, they will likely do fine. Don't put the Gold Rams and the GBR's in the same alternative tank though, will not end well. Now, while some may say that rams and corys don't work in the same tank, I'm a believer that they do and can work. Don't quote me on that, I've only had them together for about 3 months now, but no losses (or even aggression) between them yet. If I screwed up I'll let you know 
Now, the betta and Gourami are both top-dwelling laybrinth fish, meaning they live in the same area and are semi agressive. They're even the same color here. I don't know for sure, but that just looks like it's asking for trouble. THe Gourami may also be a little mean towards other fish (though I'm going off hearsay here, I've never had a Neon Blue Guarami) so keep an eye out.
Too bad you had to rehome to discuss, but they would have never worked in your tank. I recomend you work on this tank, and in a few years you try again with discuss, if you feel you're ready. No community tanks for them though.
Besides that I can't see anything that I'm qualified to give advice on here, so good luck!
