Its my understanding that Rainbows do school and should be kept in groups of at least six. True they are not from the same location but then again neither are the Congo tetras. I was more concerned with fin nipping more then anything else since Angels with torn fins don't look nice.

Serpaes and some of the other deep-bodied tetras can be fin-nippers if you have fish with long fins (like angels). I've never had rainbows so I can't comment on those.
I've done lemon tetras, black neon tetras, and rummynose tetras with angels and didn't notice much of a problem. If you do get tetras, it's best to keep them in groups so they nip at each other and not other fish.
ALWAYS quarantine new fish! Any new fish could wipe out your existing stock if they come in with a disease of some sort.

I've kept lemon tetras with Acarichthys and Guianacara and they worked well.
Never had a problem with them nipping at the Acarichthys fin trailors.
And as Ryan said, any new fish can take out a tank, if not quarantined.
I like to quarantine fish, and add water from the main tank during the sequester, you never know if your original fish are relatively (but not totally in an epidemic situation) immune to something already in your main tank, the new fish aren't, and if the the new fish break out, you've time to treat in the sequester.

My understanding of rainbows in the wild is that they are shoalers. So they exist in loose congregations, but don't tightly school like many tetras will. I have 28 serpae tetras in my 75 and they are never more than a couple inches away from each other. The bigger tankmates, while not predatory, keep them together. And that is different from when I only had 9 of them in the 75. They were more spread out. I have never had an issue with serpaes nipping fins, though most small dithers have the capacity to be nippers. They are definitely more concerned with what their own species is doing when in bigger groups of 15+ IME.
If torn angel fins is a concern, you could do without the dithers all together. I bred and raised angels for years and they never needed dithers. They are bold little fish that basically act like large dithers themselves. So you could keep it at just the angels and geos and be done. There also isn't really a need for other bottom dwellers as the geos will spend a very large amount of time sifting the sand to forage.
And of course quarantine is always important.

Im content with the Geos as my bottom dwellers and the angels basically spend their time mid level accept at feeding time. I really like Serpaes but they have a notorious reputation so I really have to give it some thought.
