"[h]ow did he die "for our sins"?"
jesus is referred to as the "lamb of god" because lambs were used as a sacrifice. sins were ceremonially transferred unto them before their sacrifice. no animal could bear the sins of mankind, so god sent his only son to be sacrificed for humanity.
"countless others were crucified and never mentioned."
jesus was without sin and the son of god.
"[w]hen he died for our sins, does it mean we can sin as much as we want and always be forgiven?"
no it means that he opened the gates of heaven so that the righteous could enter the kingdom of god. unrepentant sinners still go to hell. fire and brimstone, pain and eternal suffering. but, no one can say for sure whether another is dserving of hell or will surely go there, that's god's job. it's actualy a big ol' sin to do it, so those televangelists have quite a bit to answer for!
"[d]oes it mean his death was caused by our sins of today?"
technically because he died for the sins of humanity any sins were taken into account as god knows all, sees all, tells very little.
"[n]or have I ever understood the concept of "original sin"."
yep, according to catholicism we're born with the sin of adam upon us. (this led me to curse my parents as i took baptism, since it wiped away original sin, as a clean slate and as such would have come in handy much later in lfie as opposed to being wasted when i was a freakin' baby!)
