You should do your touch typing lessons as often as you are capable of without hurting your fingers! As with everything else, regular training gives the best result. Most people will probably get the best result by distributing the lessons to several days in the week rather the doing a lot of exercises in one day. It is a good idea to put your touch type training into a calendar to be sure to remember to do them. If you don't have a calendar you can use the Google calendar which is free and easy to use. In this way it is easier to remember to do your exercises.
When you reverse-engineer someone else’s code, testing each line to see how it works, you get a better understanding of the big picture. Thanks to the tons and tons of open-source code that’s out there, you can learn just about anything by examining someone else’s (flawless) work. Just remember to share your code back with the community if inspiration strikes and you improve a part of the program you were fiddling with.

As with everything else practice makes perfect. You can follow your own progress by pressing the button 'Statistics' in the top right corner, you will be able to follow your progress online after each lesson.
