I need to erase my hard drive. But the drives are grey when I go to Disk Utility.
Restart the computer with the Command and R keys held down and use the Disk Utility from there. If you're going to sell or give away the computer, press Option as well.

When migrating from time machine to my new hard drive, it migrates the first back-up I made several years ago. How can I migrate the latest back-up ? I need time machine to migrate the latest back-up. Should I delete the older back-ups ?
As noondaywitch says, it should use the latest backup.
Where are your backups (external HD, Time Capsule, etc.)?
It sounds like there are two separate sets, and you're not connected to the right set. -

I have a Mac Pro OS 10.7.5 and have a DVD+R disc with files on it, but it ejects the disk after about 10 seconds--what to do? How can I get the data off this disc? I can see it has been already burned, so files are on there?
Try cleaning the lens and see if that will restore functionality to the DVD drive. Use a DVD lens cleaning disk, if you have a can of compressed air, shoot some into the slot or wrap a fine microfiber cloth (eyeglasses cleaning cloth) around a business card and insert it gently inside the slot.
If no success, make an appointment at an Apple store genius bar and get a free diagnosis from them.

iTunes is telling me that my iP4 may be damaged and can't be activated, but I was using it when it turned itself off, so how can it be damaged? I even managed to download photo's from it whilst it was turned off, so there was clearly some functionality before I restored it. Is anyone aware of any problems with the Apple's servers currently?
Things fail sometimes.
Was it jailbroken or "unlocked"? -

It wont fix your problem, but may tell help troubleshoot, why it is freezing iTunes, especially when the Pending and Realloc numbers are high.

I upgraded to Snow Loepard OS. But not all the information in the address book was transfered. How can I recover the lost information from my old address book?
No I did not make a copy of my address book.
Some information was moved over, many did not.
I do not see a pattern.
I think all the info is still on the hard drive, I just don't know how to recover it. -
How can I change the delivery address from the USA to Switzerland?
Don't belive you can do that but try changing the Print Produces Store from the USA to Switzerland in iPhoto's Advanced preference pane and see if the order will go thru. However, I believe you'll need a credit card with a billing address in the same country as the delivery address. It's worth it a try.

I want to setup LR on my new laptop. I have the serial number from my latest purchase but not the original purchase of LR3. How can I recover the serial number from my original LR purchase?
If you did register it back then, open your Adobe account with your Adobe ID and you will find it there: Find your serial number quickly
If you still have it installed, open the System info in Help menu or look here:

How can I eject the disc and start over and get into the OSX system?
XP isn't supported in BootCamp, you'll have to use the free VirualBox or one of the other commercial virtual machine softwares to run it in a window on OS X. The performance isn't going to be good enough for 3D games or heavy CPU ones, but good enought for most general use software.
Apple doesn't supply the hybrid MBR and hardware drivers required to run XP in BootCamp any longer. If you were on Snow Leopard 10.6 it's still possible, but not Lion or Mountain Lion.
This is what you do to resolve your problem.
1: Hold the power button down to force a hardware shutdown (emergency use only use the Apple Menu > shutdown all other times)
2: Press and hold the option/alt key on the keyboard.
3: Boot the computer and enter Startup Manager
4: Keep pressing the eject key on the keyboard, the disk will eject.
5: Select OS X to boot from by clicking on the volume and the little arrow that appears.
6: Set Startup Disk in System Preferences to OS X.
7: Head to BootCamp Utility and use it to remove the BootCamp partition.
8: If you used Disk Utility, then use that to remove the second partition and absorb the remaining space back into the OS X partition.
9: Install VirtualBox, if on 10.8 you migh have to control/right click and "Open" to bypass Gatekeeper controls for the installer and/or program at least once.
10: Read the instructions how to setup and use VirtualBox. -
