Answer 1

Check that your computer is compatible with Mountain Lion.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Model Numbers                  Computer Compatibility - Apple 
Check to make sure your applications are compatible.

Do a backup before installing.
Boot using the Recovery volume (command -R). Use Disk Utility to Verify/Repair  the disk and run Repair Permissions.
Restart normally.
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again.  You can make a bootable DVD/USB stick to install using this free program.

If you need/want more RAM, the 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM serveral times from Other World Computing and have always been very satisfied with the product and service.
