First buy a tablet. I won't give recommendations because mine's pretty old and it's the only one I've used so I don't know how it compares to others, but you should be able to find plenty of reviews or guides. Go for one that's relatively inexpensive (but not poor quality, just not fancy) and an average size. Once you have that it should be pretty straightforward to get it working. Then you need a program to actually draw in, I think SAI is great for beginners since it's pretty simple to figure out but you can still do a lot with it. You can find a free download online. You can use whatever you want but I don't recommend jumping right into something complicated like Photoshop. And then once you have a tablet and a software, you're all good to go. Just start drawing.

I think that's just a matter of getting used to your tablet, and CTRL+Z-ing until you get the line right. It happens to me too.
