I will answer these to the best of my ability with what I know.


 * 1) 1- His hollow is his Soul reaper powers. Zangetsu is a 2 in 1 power. I think Isshin took White so Masaki wouldn't die, but I could be wring there. There's nothing that says you can't be a fullbringer of Quincy blood, so I guess not.


 * 1) 2- As far as we know Gigai work the same as human bodies. Rukia almost fused with hers because (I think) of the Hogyoku, so we can only assume something similar was done with Isshin, or that his was designed to to stabilize his soul in it.


 * 1) 3- By successfully becoming a Soul Reaper his spirit chain means nothing. If he hadn't found his powers it would have been a problem, but he did so it's fine.


 * 1) 4- He doesn't have full Quincy powers, but a piece of them. It only really lets him use Blut as far as we know, and not even on purpose really. If he was trained as a proper Quincy, this might not be the case, but since it's just part of his soul, it doesn't seem to do much.


 * 1) 5- Fullbringers just have to have mothers that were attacked (I think bitten) by hollows. He meets this criteria. Like mentioned before, there don't seem to be any rules against Quincy born Fullbringers. There's a chance they would never even find their Fullbring if trained as a Quincy, same as how Ichigo didn't find out until he was told.


 * 1) 6- See number 3.


 * 1) 7- He was born with a hollow attached to his Soul Reaper powers. There was no need to use the Hogyoku since he already had a hollow (A rather powerful one at that) attached to his soul from birth. It seems it's just a matter of unlocking his powers. The more he used Zangetsu the more hollow like he became because Zangetsu, being part hollow, wanted to take over Ichigo. By learning to control his power better he became a Visored. I don't think the Hogyoku's power can be passed down, but there's a lot of crazy stuff that can happen with Ichigo's kids because of the mashup of his powers.


 * 1) 8- He's a substitute Shinigami. It's just a designation for humans who can take over Shinigami duties. So, humans with Shinigami powers.
