you don't really need to trucebreak as long as you get a foothold in the British Isles early (so you don't have to mass heavies which you won't have the money until ~1600 in most cases)
Portugal is down in 2-3 wars, and you can remove Castile's coastline in 2. France and England don't take exploration 1st so you have a slightly more generous clock to deal with them.
Here are my moves right after revoking - WC finished in 1654 so pacing was okay but I still made some mistakes -

all core return. It is a very useful CB for shredding down France (core return discounts from Guyenne, Toulouse, Provence, Flanders will save you ~300 DIP and 70% warscore - almost a whole 15 year truce timer) for this phase of the game. Thus you will not want to take the HRE lands of countries you have Imperial Ban on.
You don't absolutely need to 'kill' Castile early. If you restrict their income enough from rampaging over their lands, they won't be able to subsidize 4 colonists which is where the real colonial problems start happening.
You will want to core the French provinces all the way to the Atlantic, add to empire, so you can eventually add Galicia and Navarra to the empire, which will easily eat Portugal and Spain for you. Galicia can also handle north africa (though not easily, you will need to babysit them) - they have religious ideas so once they convert the Berbers its ok, but it will take a while for that to happen.
