I don't personally believe we get a "body" or anything like that. Whatever is next is another plane of existence and what we need there won't be what we need here.
I don't think we worry about what's going on at home, where our loved ones are that died before us, anything at all. I believe we are at peace in a manner that we can never know here and that we feel God's love and Word in the same way.
I know one verse says we spend eternity singing His praises and maybe we do but I sorta doubt that. Seems like even God would get tired of it after a few thousand years.
It may be that if there is an afterlife, what it is like is completely incomprehensible and inexplicable and indescribable to any living person, because it is as different from our present state of being as this from the womb.
