Take a look at hexdump. Its -C does 1. You'll probably need -e for 2.
3 and 4 will require a decision on how you're splitting your display
into lines because that determines what offset strings you can search
for. 5 and 6 will also be affected as there will be line breaks to
deal with, so it would be better to use an editor in parallel for
performing those searches on the original file rather than the hexdump.
