Neither the Hebrew scriptures, or the Christian Greek scriptures say any of what you've posted. Where did you learn these things?
What
Hades refers to in Greek isn't actually controversial, though it is telling that it's the standard translation of Sh'ol in the LXX, which means that's surely what the NT authors are up to. As for Sh'ol, it gets several mentions in the Hebrew scriptures, and all indications are that the identification with the Greek Hades is a pretty sound analogy. It's meant to be the place from which the Witch of Endor summons the shade of Samuel, for example, in a necromantic ritual much like the one Odysseus performs in the
Odyssey to talk to Tiresias, who is in Hades.
Then there's the collection of texts written in the Hellenistic period between the Hebrew Bible and the NT (e.g. the
Book of Enoch), which give detailed accounts of Sh'ol that show it to be very similar to the Greek underworld in form and function. The fact that those texts didn't end up being canonized doesn't mean they weren't influential (
Enoch in particular was well known to the writers of the NT) or that they don't accurately reflect the beliefs of the people at the time when the NT was written.
Abraham's Bosom, incidentally, appears to have been a subsection of Sh'ol that was something analogous to the Elysian Fields. It is mentioned in the
Gospel of Luke as an alternative resting place as opposed to the nastier parts of Hades/Sh'ol.
Modern Judaism isn't really concerned with the afterlife, but ancient Judaism did have some ideas about it, and they were not the same ideas that modern Christians tend to have, but rather pretty standard ones for the ancient Mediterranean. The thing is, you have to understand that the texts of the Bible assume a lot of cultural context that they themselves don't summarily dump on you; you have to actually do the legwork and find out what they're talking about. Fortunately, we have a good deal of literature from and about the time period in question.
