SQL Server Collation

I am upgrading SQL Server 7.0 to SQL Server 2005 and have three questions.
1.      What are the differences between Collations SQL_Latin1_General_CP1_CI_AS and SQL_Latin1_General_CP437_CI_AS (tempdb on SQL 2005 Collate = SQL_Latin1_General_CP1_CI_AS) and (SQL 7.0 database Collate = SQL_Latin1_General_CP437_CI_AS)?
2.      What are the differences between Sort order ID 52 and 54?
3.      Can someone demonstrate sample of SQL Query that will show how Sort order ID 52 and 54 acting?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

2. 52 is sensitive to ascents, 54 is not

select case when 'BibliothŠque' = 'Bibliothèque' collate SQL_Latin1_General_CP1_CI_AS then 1 else 0 end
select case when 'BibliothŠque' = 'Bibliothèque' collate SQL_Latin1_General_CP1_CI_AI then 1 else 0 end

1. http://en.wikipedia.org/wiki/Code_page_437 and http://en.wikipedia.org/wiki/Windows-1252
Basically, the same bits will equal different characters in some situation between the two codepages
