As for the discussion of charagraph stuff, I just "cut out" my charagraphs from images I find on Danbooru via image editing able programs like GIMP (which I'm currently using). I'm not skilled enough to trim characters right to their borders, and the process takes a long time too (not to mention finding a suitable image, especially so for certain characters). I suppose I could find a set of source images I used, if you want to edit them yourselves (I don't have anywhere near a complete set either). Although I'd be just as interested in learning how to trim images right down to the borders, myself.
Also, I'm pretty sure this has been suggested on this board before, but maybe a charagraph set from avatars used on this site? Dunno if that's plausible / possible.
