The biggest learning curve with tablets is the new concept of hand-eye coordination -- you're looking at the screen but your hands will be drawing on a different surface. Pen pressure on a tablet will also feel different from pen pressure on paper. All it takes is lots of practice and continued use until your mind becomes used to it. Get a feel for how sensitive your tablet is and be sure to adjust the sensitivity settings to whatever you're most comfortable with. Pay attention to what buttons and functions you use the most and set the keys on your tablet to make switching tools easier. Once you can do on a tablet anything you can do on paper, you're all set to look at tutorials for more in-depth guidance for specific effects.
No rush with the tablet, it always takes some time to really get used to it. Anything small and simple will work. I got used to my tablet by coloring in lineart. Some friends mentioned they started by blending colors together. I recommend writing for later, once you give it more time. I barely recognized my own writing when I first tried, haha!
From my own experience: If you can draw, using a tablet is a huge advantage. Once you get used to it, to a point where it's no different than drawing on paper with an actual pencil, that's when you've arrived.
