With regards to generational influences, I wasn't sure if they're as relevant since many people will have the following degree: Pluto 8.5° Saggitarius, which is in this case in the 3rd house conjunct Antares and Opposite Aldebaran in the 9th house.
Yet I saw some people with this who were totally useless.
Should you read these in the context of house positions of all fixed stars too?
Higher planets and transneptunians as well as centaurs are not for everyone. Some people do not make any use even of their personal planets let alone of these. It is you who decides what and how you are going to use in your chart. Yes, most people let them be generational. This does not obligate us to behave like that. We are here to use what we have for the purpose. Absolutely everything in endless cosmos can be used by a Zevist.
This chart is very difficult to read. Almost every planet is conjunct or opposite a fixed star, sometimes multiple. Albeit, they appear to be mostly a benefic influence.
Does a chart's "luck" only become activated once the individual takes control of their own destiny?
What you call "luck" is basically what I everywhere call Destiny. You have to "open" it up and deserve by your efforts in this direction. Usually those of spirituality and work for the world (for ToZ, for Gods, investment into learning astrology). Every Star has its beneficial side which is the way to serve the good of the universe through it. When we try to use something (whatever) only to serve the higher purpose of bettering the world, it stops being a problem and starts being a gift.
If you have a lot of Stars just try to find their higher influence by analyzing the life of those who managed to use them for greater purpose, if you manage to find such info in the internet. Or at least find those great people in whose charts you find them and see how they worked out. For example, here is about Zosma.
Here you can see that it has plenty of rather nasty characteristics which are very well seen in the "reap" phase when we reap what we collectively sowed and what we sowed was bad:

Yet, here is also mentioned its different quality:
"It can thus be seen as a source of strength in a horoscope, showing a somewhat critical turn of mind but with a constructive intent behind it so long as the aspect and the planet on it in the horoscope are in harmony with it.
If that not be the case, then Zosma is calling for the cultivation of constructiveness if the subject of the horoscope wants to live life harmoniously. Given that proviso, it is generally held to be ‘benefic’ by any authority, most of whom go so far as to promise high government or managerial office on account of it."
And I saw it in powerful charts as well as in extremely talented ones without any egotism or related bad thing in "reap" phase. Rare but still.
This is only one example. And the list of the Fixed Stars goes. Most are searchable online, but even if not or if you feel that internet stuff is not very trustworthy or watered down, you might analyze several great charts of great people with it to see it blatantly.
With regards to Centaurus objects, I will look into it, however Chiron is conjunct Pluto, and making 0° orbs to the CR, co-ruler, bucket chart handle (Jupiter), Neptune and -1° to Uranus in Aquarius.
Is the Transneptunian stuff available in Astrodienist?
Yes, both Centaurus and Transneptunians are available there.
Go to atrodientist. After you entered the data go to Extended chart selection page. There you go to Additional objects section in the bottom of the page and press Shift and choose:
Vertex
Lilith
Pholus
Eris
Haumea
Ixion
Makemake
Orcus
Quaoar
Sedna
Varuna
Prenatal Solar eclipse
Prenatal Lunar eclipse
Vertex and eclipses are needed in relationship analysis as is written in ToZ, all other recommended objects are Transneptunians and Centaurus. I watch Lilith because Lilith is Lunar Perigee. Perigee Apogee axis is also interesting in regards to the Fate - Destiny forces. Yet I first look at other more crucial things. These are more subtle.
Then you go to Display and Calculations Options and choose these:
quintiles/biquintiles (72°, 144°)
semisquare/sesquisquares (45°, 135°)
Thus you will see creative aspects and Golden Yods if any.
I recommend this reading about transneptunians:
When Uranus and Neptune, the first outer planets, were discovered, one way of understanding these new energies was the concept of a “higher octave.” According to the theory of higher octaves, the energy of an inner planet gets expressed at a more spiritual level. Uranus was considered the higher...

As for centaurs you only need to know the mythology about them because it says it all.
Good luck with such a chart!
