Hi Hachuu and welcome
How does one "get started" or maybe more pointedly phrased - "could you show me the way to the Way?" ... what a question; however not easily answered.
As a suggestion; at first, go slow, be sceptical but open to listen, be patient, be diligent with your practice - there is no one correct way. (agree with @theLearner - in the beginning less is more.)
i would suggest selecting a few books/research to give yourself a good understanding of the Daoist landscape. Language & terminology, philosophy, practices, rituals etc. are sometimes barriers to westerners - persevere!
Find a few authors, teachers, gurus (beware the snake oil) that know what they taking about and resonate with you!
From your book selection - my 2cents
*Chinese Shamanic Cosmic Orbit Qigong by Zhongxian Wu :
Zhongxian Wu i believe is the real deal. have read the book and it provides a sound approach and finer detail to performing this form of Qigong as well as some great bread crumbs to follow. It however will not provide yourself with a detailed understanding of the theoretical background of Neigong, Qigong, the Dao, etc which you may be seeking.
*Understanding Reality by Louis Chang:
i would rather suggest that you read an alternate translation by Fabrizio Pregadio - Awakening to Reality(Wuzhen pian) as he provides clear explanations for each of the poems allowing the reader to "decode" some of the - as you described - "cryptic vocabulary"
Some of my first introductory books and authors
*Damo Mitchell - the philosophical art of change [Pub: singing dragon]
- Heavenly Streams - meridian theory
- White moon on the mountain peak - The Alchemical Firing Process of Nei Dan - (if you reading Awakening to Reality you'll understand the White moon reference )
*The Mages of Java - Costa Danaos - interesting side note - search documentary "Ring of Fire" & John Chang (Dynamo Jack) on youtube. I get a smell of blended fiction and non-fiction with this book - a great Sunday read however!
*Opening the Dragon Gate - Thomas Cleary [pub: TUTTLE ]
*Lao Tzu - Dao de jing - challenging read - would park this until you get a handle on terminology, symbolism and basic philosophical understanding.
*Secret of the Golden Flower (alt. Awakening to Reality or Sitting in Oblivion)- 2 versions offer a clear translation.
*Various other ancient daoist texts and canons - some of which are available on this site
authors to look out for i found to be useful:
Alan Watts
Alexandra David-Neel
Livia Kohn
Fabrizio Pregadio
Jerry Alan Johnson
Thomas Cleary
Damo Mitchell
Yang Jwing-Ming
.. many more
i hope this provides a small spring board ... and a point of departure in some direction.
