Assuming your space ship survives engaging with the accretion disk and any spaghettification issues:

(1) I’ve read that the crew can’t tell if they’ve already crossed the event horizon. There wouldn’t be a point where some crew member would analyze the recent path and what they could see what’s outside the windows on the way and go “oh sh#t”?

(2) Black holes lose mass through Hawking radiation. Once you cross the event horizon, you seem to be part of the black hole. So couldn’t the part of the black hole that goes away (to balance the outgoing HR) be part of you? Assuming you had super space sensors, could you detect missing parts and conclude you’re past the event horizon?

One might think that the outgoing radiation would hold information about what fell into the black hole. However, this information is only partial and not very useful. This is because, irrespective of what went into the black hole, from outside the radiation would appear very close to black body radiation (Hawking radiation).

Another way to look at this is - every outgoing particle should still be entangled with the rest of the interior of the black hole. Although we can measure the outgoing particle but one side of these quantum entangled states are inaccessible to us (the ones that are behind the horizon). So, merely measuring the outgoing particles will not give us complete information about what really fell in.
