DBZ episodes no longer run on CN or hardly at all on any TV channels, you would be lucky to find it now a days. Although Toonami came back recently, there's a good chance episodes will be on there.

I think so...
watch whole episodes in DBZ-Zone.org you should find Bakugan there
Google.
dbz.tv
the DBZ series is finished so they are finally continuing DB Kai
Theres a special website just for Dragon Ball Z called DBZ Media.
257 episodes have been showed on cartoonetwork. but on DVD 251 because it was remastered and uncut.
Anywhere if you google the episode's name. Just type in Watch Dragon Ball Z episodes (and depending what language you're native in, type in that language sub) And it should take you to a whole bunch of sites that will let you watch for free. Hope I helped;)
In some episodes of DBZ Gohan goes to college, if that is one.
