Those aren't the idolatrous parts. The idolatry happens when you exalt Mary and martyrs. And when you perform empty repetitions out of superstition. Crossing oneself isn't Biblical, for example. Moreover, it's the concept that people can earn salvation, be saved after death or lose their salvation you teach falsities. So maybe some of what you're doing isn't idolatry but a misunderstanding of fundamental means it's all for naught anyway.
