"Olivander's in the only place to buy wands" (paraphrased quote or 
whatever you call it.)
- I'm assuming that 'only' refers to 'best' - the only place worth 
visiting, simply because it's the best. (or possibly the only place 
in Diagon ally).

As For Peter Pettigrew and the houses of the Marauders. People can 
change, character traits that are in the background of a personality 
at a young age can come to the fore in adulthood. It dangerous to 
judge characters as adults to how they could have been as children.
Also, looking at Hogwarts student lives of Harry's age for reference -
 I can't see how four people could become the closest of friends 
without being in the same House.
The only none Gryffindor 'friends' Harry associates with are the 
likes of Cedric Diggory, Cho Chang and the like. He only knows them 
through Quidditch and / or shared lessons. But to be 'inseperable' as 
the Marauders were made out to be I think they would have had to be 
in the same house - just to give them chance to get to know each 
other well enough to get that close.
