As I see basic "set" is the one. There is nothing more, to me, to get over that two chucks that comes with T18 basic.
Looking at centrotec bits, I think it will not accept my screw bits with circular groove at end of the bits. In that case I have to use "FastFix Keyless Rachet Chuck" that comes with basic package and put into it my "Bosch hex fast-fix" for the screw bits. It will add a lot of use of that FastFix chuck.
In this case is it make a sense to order one extra FastFix Keyless Ratchet Chuck because later on I will not be able to re-order it any more.
Correct, Festool really has no appropriate provisions for standard ball-detent power bits (other than securing them directly into the jacobs chuck).
Only standard wire detent insert bits and their unique centrotech design.
Granted, the ball detent bits will fit in the gear shaft as well as the bit holder.
However, they're designed for wire detent insert bits, therefore, the outcome is a bit wobbly.
Here's a good rundown or two of what's going on with that:

However, Snappy makes a power bit holder that will go into the centrotec
chuck. It's probably exactly the same looking as the bosch one but with a centrotec shaft.

You will have to likely order it directly from them.
Another option for quick change ball detent power bits comes from
Wiha called the Centrofix (formerly rapidfix). You'd have to put that in the jacobs chuck, but I'm throwing it out there because it's got a slimmer profile.

As for Festool chuck availability, you will be able to purchase them for quite a while. I believe their gurantee stipulates that any Festool part will be available for 7 years after discontinuation of a tool (10 years for UK/Europe?). Röhm makes the chuck in question, and their production plant isn't going anywhere anytime soon.
Anyway, speaking of chucks and if you can afford it, I'd reccomend thinking about the "eccentric" (offset) chuck, the right angle chuck and the 3/8" socket adaptor chuck. You can always purchase them later.
