Artwork Creator Software

Manga software…do you know any?????
I have a script, characters, and a storyboard. I want to “try” making a manga. It;s my first time. I bought a software called “Comic Book Creator” (Empowered by: Planet Wide Games).
As a software it’s not bad but it has a lack of balloons and other effects. I’d like you to give me some tips regarding a better ‘downloadable’ software and some tips on making manga. For example I would like to know how is it better to input my artwork>> is it better via a graphic tablet or by scanning my paperwork?? Also how can I make my artwork totally black-and-white??
Please if you can help me in all of my questions, I’d be very grateful! Thanks in adavance!!!
>>If you can PLEASE send me either the links to download the manga program or the name of it<<
i don’t know if you can download it anywhere but i have this one called “comiclife” on my mac….i don’t know if you’re using a mac…but it’s easy to use and you can do lots with it (to be fair I’ve only played around with it a bit so I’m no expert but I think it’s good…)
scanning your work must be better than graphic tab unless you’ve gotta really good one…but I spose that could apply to your scanner too…
I’ve just had another look at the prog and their website is www.plasq.com
