Question: Do the pieces of Voldemort's soul (in the Horcruxes) obtain all of his memories, including those from days after they were made? For example, would the Tom Riddle in the diary horcrux remember Harry killing Professor Quirrell a year earlier?

Answer: No, the Tom Riddle that rose from the diary had no recollection of anything that happened after the piece of soul from which he came had been severed from the rest of Voldemort's soul.

Question: Is it just me, or do the Expelliarmus, Everte Statum and Rictusempra spells all do exactly the same thing- knock the opponent backwards? And why doesn't Expelliarmus disarm the opponent?

Chosen answer: The spells have different effects, not necessarily visible, they're just cast so strongly that the spell has the added effect of throwing the opponent back.
