EU2 Question - Techs

And here's the North American colonies. I haven't had the opportunity to wipe out the other natives since I have had stability problems, but that's the next piece of fun.

Here's Africa. These are just bases for naval exploration. I have a couple in S America too.

And here's the latest theatre of English operations. I have colonized Jakarta and am only two colonists away from making it a city. Once I've done that I'm going to spew out troops to kill natives and colonize all the spice islands.

I've even discovered New Zealand.

Any advice?
