If you don't keep Sabbath and/or eat Kosher but observe Jewish customs and some laws, then you would be considered traditional which means not religious but keeping customs and a few laws. The difference between that and Conservative, is that you don't consider yourself to be conservative or believe in that nonsense, you openly admit that you are not religious. Most Sefardim I know are in this category as Sefardim rightfully see conservativism as bull crap. Yacov Menashe Ben Rachamim would be considered as Traditional. Modern Orthodox means someone like me, who observes all the Jewish laws and is Misnaged in origin (or the Sephardic equivalent of Misnaged). I honestly have never figured out what is the difference between Modern Orthodox Machmir and Modern Orthodox Liberal. I know that Yeshivish means your a Yeshivish black hat learner type.
