c2k - I didn't see anything in the volumes, but the perfect guidebook 2 does indeed put the extra "h" in there. So well done (it doesn't change the pronunciation of the name or anything but I'll start putting it in from now on.
Alterno - First of all, you need to realize that it's not going to be quick - "soon" is going to be defined in years, not months.
Second, you need to learn all three, but obviously start with hiragana and katakana. With a lot of study you can learn them both in about 3 weeks, and reading them should be second nature after about 3-4 months. Also, FOLLOWING THE STROKE ORDER IS CRUCIAL!
Finally, you need to get a feel for the flow if dialogue and how to write it, not just going from bubble to bubble and translating what's there. That includes sometimes writing english that conveys the "emotion" of a sentence (i.e. surprise, disappointment, anger) rather than the literal meaning, while remaining true to the character and their personality.
Xiphias - I'm enjoying Shion more than I thought I would, but it may just be because I'm getting to learn about Shogi terms

I'm interested in seeing how the murder mystery is unraveled and watching the characters mature.
Shion, Queen and Carrera are kind of interesting to me because I haven't read much "real-world" type manga, so it's been a new experience for me. Agharta confuses the fuck out of me, though. I read the older chapters in preparation for translating the one you asked for and I think a physical question mark formed over my head for a few minutes ;D
There's no one book I can really recommend to a new student of Japanese - I'd advise you to just absorb as much as you can from whatever textbook you're assigned. If you've got a choice, pick a professor with a reputation for working their students extra hard, it will be worth it.
Oh, and practice your kana by writing each one 50 times and saying the sound out as you write. E.g. Write あ, say "Ah"
Again, FOLLOWING THE STROKE ORDER IS CRUCIAL!
Since you're here, do you plan on continuing all the series you've started or seeing which ones garner the most interest and then just scan those? I've noticed you started discussion threads for them, you gotta advertise those when you put the releases out
