If you want to get further into manga, don't waste your time reading multiple Shonen Jump series. Aside from Deathnote, they are all the same, with the only things changing being the characters and the method of how they save the world. If you read more than one, then you're really just wasting time because you will be able to figure ouy exactly how everything will turn out.
The Jump series' everyone's going on about right now are Naruto and Bleach. Dragon Ball Z is the classic, but is really long. It's not that any of them are bad, per say, but once you've read one, you've read them all.
Personally, I would recommend FLCL, Cowboy Beebop, or Nausica, since everybody seems to be going with more mainsteam titles.
