Not sure I quite understand your question, but here goes:
1.) The traditional Jewish forms of Temple worship (bowing, incense, animal sacrifice, wine libation) are prohibited vis-a-vis an idol, regardless of whether that's the normal way of worshiping it. "Serving deities in the manner they are conventionally served" prohibits other forms of worship.
2.) An item sacrificed to an idol ("takrovet avoda zara") becomes prohibited from all benefit, e.g. if a cow was slaughtered to Baal, not only is the meat not kosher, but a Jew can't even sell it. There's a discussion in the medieval commentaries whether this also applies to objects used in deity-specific forms of worship, or only the traditional Jewish forms.
3.) Generally, if the Torah says "do worship in the form ABC", that means it's allowable -- and obligatory -- to do so, regardless of other considerations. Do you have an example to the contrary?
4.) Setting up a "matzeiva" -- a tall, single stone on which libations are offered -- was done by the Patriarchs, but when the Torah was given, it was prohibited. (See Sforno Deut. 16:22) But we work with Halacha as we know it from when the Torah was given.
5.) I assumed your question was one of Jewish law, "does that change our practice?"; and not a question of philosophy, "if Judaism is so different from idolatry, how could it share so many practices"?
