Al-Iskander
Warlord
If I may be excused a fanboy moment, this is the coolest RPC ever. I've always wanted to do something like this, and I'm glad to see someone else try it.
Now for suggestions that may or may not be useful:
Religion
1. If you don't bring Buddhism with you, you might have the chance to get all of the other religions by their natural spread and make an unorthodox attempt at a culture victory, if it's not too late for that.
2. If you do bring it with you, you can switch to Organized Religion (if that's an option?) and build up Brazil's cities faster. Those cities will need their buildings quickly after independence. (If you already have the cities well built-up, my apologies, I don't have Civ here and I can't check the savegame).
3. You don't really need theocracy, for any reason. Big land wars against you are unlikely in your current newly-isolated situation, and the more religions that spread to you, the better.
Boats
I have no idea, as I've never gotten to play BtS (only three months more!), but I'd move them into Brazil just to be safe. My guess would be that it works like the spawning-Civs in RFC, that is moving the units away would be advisable, but someone who's actually done this before would be better qualified to say
Independence
You have a comfortable treasury cushion. I'd say wait a bit, but not too long, as in the long view sooner will be better than later.

(Edit: if you did it for roleplaying reasons, ie. Brazil first, that's OK ofc
