So, I haven't found much Illustrator help for my needs. This is why I turn to you. This is what I can do so far (I used the brush tool only):

My questions:
How can you color it it (the paint fill won't work well for me, it doesn't fill between lines, it fills the area a line surrounds, is there a way to fix this)? How do you erase spare lines (see jawline for a careless bump or two)? How do you connect lines together (see top of hair)? Can you add speech bubbles, etc.?
Basically, can you create an entire comic in Illustrator, or do you need Photoshop intervention?
I've used Flash forver, but the wobblyness of the lines is starting to get to me. I could create my entire comic in Flash, so I guess I kind of want Illustrator to be an everything-in-one program. Plus, if everything is Illustratorized, then enlarging images will be really easy.
Please help, and thanks in advance.
