Answer 1

The errors that you found in Disk Utility may have led to your OS becoming corrupted. You may eventually need to reinstall the OS using an Archive and Install, but you do want to make a good backup before attempting this.
You might want to run the extended version of the Apple Hardware Test and see if you get anything in the form of an error code. If you do, then you have a hardware problem which Apple will need to fix under warranty.
If the AHT shows no problems, you might want to try running SMART Utility:

It is somewhat more critical than Disk Utility and may detect impending hard drive failure sooner than Disk Utility will. If your drive is actually failing, then it needs to be replaced. If your drive has started to fail, it could easily have developed the errors that Disk Utility repaired and caused software corruption. Remember that Disk Utility only repairs the drive's complex software--it cannot repair it physically.
You could also try creating a new user account to see if the problem is widespread or just in your main account.
If SMART Utility shows no problems, then the next step would be to try reinstalling the OS using the Archive and Install option.
Good luck!
