Spiderman questions

been reading some old amazing spiderman comics and annoyingly some of them drift off and finish the story incomics i don’t have. can someone provide me with a summary for these two plotlines?

a) so spiderman finds this giant transporter thing in central park and then zaps off, then comes back in a new costume and doctor connors under his arm. what happened in between? was it like in the tv show?

b) so parker finds debra datring this really annoying jerk. then a little later he’s gone and she moves away or something. what happened?
