>How would a star be affected as you siphoned mass off of it?
If you are smart about it you first take off the "pollutants" which are heavy elements such as Iron. Only put back the hydrogen to make the star more efficient and last longer. What would happen with a star if you did that is that it would slowly shrink down to becoming a red dwarf and then a brown dwarf and eventually it'll just be a gas giant. Every stage has an exponentially longer lifespan.
>How would vast amounts of stellar mass be stored prior to use?
The most efficient way would be to store it within a supermassive black hole if preventing entropy is your goal. If you're a low-tech species then storing them all into artificial gas giants is also an option.
>How would it be converted into usable energy or materials?
Depending on how advanced your technology is you could use the hydrogen and helium from the stars to fuel nuclear fusion reactors. A more advanced species would use matter+anti-matter annihilation. The most advanced species would throw all matter in a supermassive black hole and use the hawking radiation that gets emitted to power their civilization.

Yeah but only an insignificant fraction would be used.

You could harvest that energy needed from the stars as well in a process known as starlifting where you use the star's energy to make it slowly spew out its material from the top and bottom of the star which you can gather up and store in gas giants of black holes to minimize entropy.
