Answer 1

You can't repair the start up disk while on that disk. You need to boot from the install disk and then run disk utility from there. Restart your MacBook holding down the C key while having the disk in the drive. Then use disk utility to repair the disk. This happens once in a while. Unless it happens a lot I wouldn't worry.
Here is Apples doc concerning this. Mac OS X: Using Disk Utility to verify or repair disks
