IBERIA

In a couple of weeks, I will be flying with Iberia from Amsterdam to Almeria v.v.:

AMS-BCN Economy
BCN-ALMERIA First

Which FFP should I actually join for these flights. Are there good promo's?
I will probably fly Iberia not often again. So I am thinking of joining another programme than IBERIA PLUS, which is a good alternative to my KLM account.
Are there oneworld programmes worth it? Or is Qualiflyer than the deal for me?

And how is Iberia Domestic First Class? Do you have lounge acces in Barcelona?

Thanks!
