Here is a couple tuts that more or less explain line weight and what it does. Having a good understanding how to use line weight is key to good inking.
in this first one, I personally find the girl narrating annoying, but it is pretty informative, and she does go through and show you the process.
This second one... you'll have some reading to do. (oh no...) but it does contain some good info and some good photos to show you how things are done
Now, although in both of these the artist is using a traditional medium, all the same principles are used in digital works. Just be happy that a tablet will make it easier in the end,
From there on out, its all practice, and lots of it.
So don't give up, and keep working.
