I have just bought a new iMac and noticed in the security some thing called file vault should I enable this what is the best way to protect access, via the encryption key that it generates or through iCloud.

For normal home use machines, I would strongly recommend against enabling filevault. Filevault will encrypt the entire disk and requires proper credentials to access things. If things go awry, recovery is very hard and will likely end up causing you to lose what is not backed up elsewhere.
