Romantic: Ouran High School Host Club, DN Angel Action: Fullmetal Alchemist, Fullmetal Alchemist Brotherhood, Bleach, Naruto Supernatural/dark: Death Note, That's all I can think of at the mo. These are all good, in English and Japanese. These have quite a list of voice actors (quite a stellar-cast), including Vic Mignogna (Eng), Alessandro Juliano (if you've heard of Smallville, he's in that sometimes), Brad Swaille (Eng), Mamoru Miyano (Jap), Caitlin Glass (Eng), Greg Ayres (Eng). All except Swaille and Juliani are in more than one of these shows, lol. Although, Swaile (who's in Death note) is in that Aninmated version of X-Men, if you've heard of it. If you like the kiddie stuff, then I recommend Pokemon (but only up to the first two series), Digimon (probably same), and Moster Ranchers. I watched all these as a kid, so i know their worth. I even watched Tenchi Muyo back in the old days, but that doesn't count as a kiddie show, does it?

You've memorized hiragana already, so katakana shouldn't be difficult, now that you're used to the symbols. Some say it can take just a weekend if you push hard at it. It depends on how many you aim to learn a day. You'll learn it quite fast, I'm sure. I learnt the hiragana quite fast, but, funnily enough, it took me longer to learn the katakana. Yeah, it depends on you yourself.
