1. Yes, it is Kosher.
2. No, it is not Kosher.

Correct. The Torah prohibited only the actual non-Kosher food but did not prohibit things that taste like it. The Talmud states that one should not say "Ham is disgusting, that is why I don't eat it"; rather one should say "Ham is probably tasty, however I refrain from eating it because G-d has prohibited it". This implies that there is nothing intrinsically wrong with the taste of non-Kosher foods, rather that they are prohibited because of their spiritual essence.

1. Yes, it is Kosher.
2. No, it is not Kosher.

Incorrect. Kashrut is neither a matter of personal taste nor of ethnic identification. Even if one could synthesize a ham substitute that has the same chemical composition as real ham it would be Kosher; the Torah only prohibited the "flesh of a pig" and the synthesized product, despite its similarity certainly is not the "flesh of a pig".
