Yes, you have the right idea. Activated abilities can be activated any time the player has priority to take an action, unless they're specifically written to have some restriction ("as a sorcery", "during combat" etc.). However, the legality of a block is only determined once, at the time the block is declared. That means giving an attacking creature flying after blockers have already been declared won't "undo" a block if the blocking creature doesn't have flying.
