Exchange compatible -- with WindowsServer/SQLServer ?

According to
http://technet.microsoft.com/en-us/library/ff728623(v=exchg.150).aspx
Exchange 2010 SP3 will work with Windows Server 2012,
but not Windows Server 2012 R2

1. Is that correct ?
2. I assume Exchange 2010 SP3 installs its own
   SQLServer, I don't need to purchase seperate ?
3. My old server is 64bit, how can I determine if
   I am running 32bit or 64bit of Exchange 2007,
   and associated Exchange 2007 database ?

1) Correct, exchange 2010 will not run properly on 2012 R2. There is no update or SP that adds support.

2) Exchange does not use SQL server. Full stop. It's storage is a different engine.

3) exchange 2007 was supported 64-bit only in production.

 You cannot just move the database to 2010. You will have to migrate or export/import the mailboxes regardless of the 32-bit/64-bit issue.

1. You are correct, EX2010 SP3 doesn't run on 2012 R2.
2. Exchange doesn't use SQL Server.
3. If I understand you correctly here, you are saying your Exchange 2007 server is 64 bit? You probably are running 64 bit exchange. But to make sure you can run a health check in the Exchange Best Practice Analyzer then select all issues. If it's 32 bit you will get a yellow exclamation telling you so.
