The first one sounds like Shelly Duvall's Bedtime Stories. There were several different episodes/VHS tapes of this (my family had two or three different ones), so even though I don't remember your stories in particular, they could definitely be out there. Here's an episode on Youtube. You can pretty clearly see her book-filled space room about 28 seconds in: https://www.youtube.com/watch?v=05adfxrRV-Q
Well that was a nostalgia trip. You are a hero, kind stranger!
The link that was posted is very definitely the episode i saw, complete with the fat mustached man reminiscent of Greg from Magic Finger. The cartoon about the girl inviting friends over is a different series
Bump? (for the cartoon about the slumber party, not the woman sorting books as that has been solved)
Wow, somebody else remembers Shelley Duvall's Bedtime Stories!
Bump for the second one again
I have very little information to offer. It was a VHS tape which featured a cluttered room full of books sort of suspended in space, live action, with a presenter woman, youngish and dark haired, searching through various books for stories she was going to "tell" to the viewer. She found two books and it then went to animation or showing the illustrations for the stories. I have no memory of what the stories were except that I keep thinking of the Magic Finger by Roald Dahl. It is possible that one of them featured a similar character to the fat, mustached Mr. Greg from MF as that is the only image i can think of.
The second is a cartoon that was posted about before in which a boy's older sister invites her friends, "a bunch of crazy girls" over and he asks his dad to help him "block the invasion". there was also the line, "he'll be my Romeo and I'll be his Juliet", spoken by the sister about her crush. Curious to know what happened in the end although I don't remember the name of the show - it wasn't Dexter's Lab or Phineas.
