Where to find Management Packs for SCOM?
The startingpoint for finding Management Packs is the System Center Market Place provided by Microsoft Pinpoint:
http://systemcenter.pinpoint.microsoft.com/en-US/applications/search/operations-manager-d11?sort=released&q=
But, what if you are looking for a Management Pack from a third party?
There is an “Unofficial System Center Catalog” available where you can find many third party Management Packs:

Change manually installed agents to “Remotely Manageable”
Kevin Holman has written an excellent blog post with the title “How to get your agents back to “Remotely Manageable” in OpsMgr 2007 R2″:
The procedure he describes also work with OpsMgr 2012 and OpsMgr 2012 R2.
Increase Operations Console refresh rate
You can set the refresh rate for the Operations Console by setting the following registry key:
HKCUSoftwareMicrosoftMicrosoft Operations Manager3.0consoleCacheParametersPollingInterval
Values 0 – 10. 0 turns off automatic refresh and requires manual refresh via F5. The value 1 through 10 increments the refresh interval every 15 seconds. The maximum value of 10 is a refresh interval of 2 min 30 seconds. As you can see the root hive is the HKCU so this is a per user setting.

How to move SCOM databases
I found a really good article that describes how to move SCOM databases, it also describes the difference between a database that has been upgraded from 2007 R2 and one that was created during the installation of SCOM 2012:

Check Database Size
There is a standard SQL report that shows how much space a database is using. In SQL Server Management Studio for SQL Server 2008 R2 and newer, right-click on the database you are interested in and select Reports->Standard Reports->Disk Usage.
There is a good description of this report, including information about how to resize a Operations Manager database in the SCOMfaq.ch blog: http://blog.scomfaq.ch/2012/06/26/scom-check-size-of-databases-sql-standard-reports/
