Imo, the easiest way to get into it, is by just using those free typing software, play around with that for a few weeks. Then, when you get a decent sense of where everything is, and you type at like 25 WPM, just switch completely whenever you can afford to (wont get in trouble with time). Obviously, when touch typing, do not look at your fingers.
Simply making the switch is the only way you will ever learn.
BTW, I also use my left index finger to hit c. It is a messy habit. Once it gets in there it is hard to get rid of it. I am always amazed about how fast people manage to type using the hunt and peck method. I can type 70 WPM quite comfortably when touch typing, but to type 75 WPM without touch typing would be pretty impossible for me.
