This was a question for a large university in Arizona moving faculty, staff and students to Office 365.

Here are the ports from the deployment guide (note: these are subject to change so refer here to the latest Port and IP list):

*SMTP Relay with Exchange Online requires TCP port 587 and requires TLS. See TechNet for details on how to configure SMTP Relay with Exchange Online. Note: you will need to provide the SMTP server which is specific to the mailbox used for relay. See the TechNet article Set Up Outlook 2007 for IMAP or POP Access to Your E-Mail Account.

** POP3 access with Exchange Online requires TCP port 995 ) and requires SSL. See TechNet for details on how to configure POP3 with Exchange Online.

Can I lock it down to certain IP ranges, URLs/servers?

Yes, here are the IP ranges and URLs/Servers:

If you are planning to deploy the Microsoft Online Services Directory Synchronization tool (DirSync) for synchronization from Active Directory to Office 365, then we have some important news for you.

There’s a 32-bit DirSync client AND a 64-bit DirSync client available for download at the Office 365 Portal!

Download the Directory Synchronization tool (DirSync) from the Office 365 Portal

The 64-bit version of DirSync supports Windows Server 2008 x64 or Windows Server 2008 R2 Standard/Enterprise operating systems.

If you’ve already deployed the 32-bit version DirSync, there is no need to install the new client. “The 64-bit version of the directory synchronization tool shares exact functional parity with the existing 32-bit software.”

For additional information, please see the Office 365 Wiki article, Directory Synchronization tool 64-bit support.
