After you have a solid foundation, you can try and learn kicks and chambers.
However, the ONLY way to get "good" at them is trial and error. At least, for everyone I know that does it, that is how it works.
Spend 1-2 months kicking when you think is necessary and you will slowly start getting it.
Do not practice both kicking and chambering at the same time, you wont spend enough time alive to actually enjoy the game...
