HARRY CLUES ABOUT THE BOOKS: Something else is curious

I have begun re reading the Harry Series for about the millioneth 
time and have noticed a few things again (some new) this time in the 
books that bring up questions that have yet to be answered.

The first and second chapters of Harry Potter mentions the following:

1. HAGRID told MCGONAGALL about DUMBLEDORE being there to deliver 
HARRY. MCGONAGALL was all ready there ahead of all of them all day. 
Why?  Was there suspected trouble coming or as a precaution? Was 
there something else?

2. A LARGE TAWNY OWL PASSED BY THE WINDOW on Privet Drive.  Was 
someone else in the neighborhood getting an owl? Remember, Harry was 
still a baby in the first chapter and did'nt get any owl mail yet. 

3. SCARS COME IN HANDY according to Dumbledore who makes reference 
to his own on his knee of the London Underground.  Other than 
Harry's scar connects him in powers and knowledge of Voldemort is 
there another purpose with the scar that we don't yet know about?

4. Harry recalls being on the roof of the school and not knowing how 
he really got there. Does this mean Harry has ability to apparate 
and does not know it yet? Does this mean Voldemort can also apparate 
since their powers are somewhat similar?

5. There were three wizards mentioned.. who are they? A man in a 
purple bowler, a man (older) in a longer purple robe and an old 
woman in a long green robe.  Who are these people that Harry met on 
the street in these chapters? 

6. Who is Diggle? What significance is he?

Just picking up on some things that seem like they should be relevant 
to the books later on and am searching for connections of these 
things in later books. It is something to think about.. and curious.
