Eps 1-62 aired on TV. OVA1 contains 8 eps which continues right after eps 62. OVA2 which also contains 8 eps continues after OVA1. In February(2004) 2 eps of OVA3 will be released then in March 2 more and so on till August. Manga is at volume 19. OVA3 will continue at vol 15, since the anime has covered 14 vol of the manga so far. That's all I am sure of.
FYI: Naruto seemingly borrowed some elements from HxH. Though I like both I think HxH just edges out Naruto a little.
