1 they do have a heel and face announcer, heel color commentator on Marcelo Rodriguez and face play by play in Carlos cabrera, they play their parts well, because they don't rant on everything like booker or michael cole, at least the play by play, the heel color commentator is always putting over the heel antics of the wrestlers to make them look ok even though they are being buried by the likes of Cena or Orton...
2 Like i said before a little of everything, they mostly focus on the moves and they put over big moves, but they also talk about the story lines and the foundation of the match itself...
3 You mean like suplex, backdrops and stuff?, it depends on the moves, they call the suplexes, rko, gts, and some other stuff, but the AA of cena sometimes it's the "attitude adjustment" and sometimes "ajuste de actitud", so in the end it depends, but the most regular moves they are called in spanish...
4 Ok i started watching wrestling like 95, so i got the announcers like tito santana, savio vega, hugo savinovich, in that time i preferred the spanish announce team, but then in 99, 2000 i started watching in english and later in spanish (same episodes), and i liked the english announce team better, but last year with michael cole being established as the main and heel guy on commentary, it seemed to demolish my liking of the english announce team, and with booker T, it just got worse, i can't stand booker T, he is so over the top and stupid (at the beginning it was a few times, but now it's almost all of what he says), so now i went back to seeing wwe with the spanish announcing, english it's just awful sometimes...
i'm from Chile and i understand the english pretty well ( i don't write it or speak it too well, but i understand it), so that's my opinion...
