Hey Jman,
http://www.bakaneko.com (lit: stupid cat, I think, but that's just trivial knowledge) seems to be reasonably good - if the others don't work out you could give it a try. If you go to
http://www.bakaneko.com, then click on drawing tutorials (top right) and scroll down the left menu that appears till you see 'lineart (some random symbol I can't make out) photoshop' that could give you some pointers.
And if you ever need freeware brushes, filters, that sort of thing, there's a lot of them on the internet and the adobe site. (Don't know if you're looking for any, but if you ever need them you should find some there). There's some pretty awesome freeware filters out there.
God bless!
