Here my attempt, I don't know if this is the that you are finding as answer, but I believe that is alt most seems to your questions.

No se si deveria tomarlo como un complido.

Yes you taking it as a compliment.

Is this version correct?
I don't know if I can take that as a compliment.
No sé que pueda tomar eso como cumplido.
Is indefinite article necessary after como?

Works, but it's more common to use the indefinite article.

ok, thanks everyone!

No sé que pueda tomar doesn't sound too good to me. How about No sé si puedo tomar
