BlackBerry went over this at BlackBerry Jam Europe. 10.1 brings Q10 support, and that's is for major new features. There's no Android Player updates or other major features.
There will be a few small features we've heard about, like more customization of notifications (though I don't expect it to be BBOS-like quite yet). There will of course also be lots of bug fixes.
Gmail discontinued support for ActiveSync on Jan 30th. Those of us lucky enough to get Z10s on January 30th (invited to the launch party) set it up with ActiveSync, everyone else has used IMAP. That being said, IMAP supports push for new emails (but not for read/unread). If you're getting new emails more than about 10 seconds after they arrive in your inbox you might want to try deleting your account and re-adding it. I've found that doing it over the cell network works better, if I do it on WiFi I sometimes only get push when on WiFi.

If you're using the Outlook desktop software that's not the same thing as Outlook.com. If Outlook is connected to an Exchange mail server then Exchange supports ActiveSync, otherwise it's up to your email provider what they support.

Your computers/network aren't a factor here unless you're running your own email server (uncommon for a small business).
