I've been up every street, me.
Inking in photoshop - Scan pencils as a colour document at 300dpi minimum. Make sure the file is roughly that resolution when you start inking, too, as any lower and the artwork looks blurry or pixellated when printed. I presume print is the endgame, but if not, you can work with a lower resolution for the web. Try mucking about with image/adjustments/curves (ctrl+m) or image/adjustments/'brightness/contrast' for approximate inking effects, but bear in mind this is only half the job unless your pencils are super-tight.
Many recommend Illustrator for inking, but I can't speak of such things.
