If you are using outlook express for mail, just go to tools|newsgroups and load 'em (may take a while), then choose which ones you want to subscribe to.
There are newsgroup readers other than OE, but I find it convenient (read: lazy...

). If ya want to see other ways, do a google on newsgroup readers.

PS I think google recently added newsgroups to its search as well..
edit: I'm the opposite from you - I've used newsgroups for a few years, but know almost nothing about IRC. Just starting to figure it out...
