The best thing I ever did for my oldest cat, Jack, was to get him a friend. Jack was about six months old, a black and white Siamese mix. He was easily bored and, even though I was working from home, demanded so much attention that I was nearly broken down with frustration.
I brought home Rizzo, a Maine Coon mix, at the time a three month old kitten. Jack was ecstatic. Rizzo wanted nothing to do with Jack and out of unwarranted fear of fighting I kept them separated for about a week. My vet advised me to let them have it out, and, as long as no one screamed, stand back. They chased each other like maniacs for about three hours, then proceeded to ignore me for the next six months. They were inseparable then, and are still good friends today. I've since brought three more cats home - one more male and two females - and Jack was hopping-happy for all but the last. I attribute that to the fact that Jack was seven and Angus was five when I brought Angus home. It took them about a year to get to the really friendly. With the females, who were four and five months old at the time, integration took about 15 minutes.
My advice is do it early, as integration only gets harder as the "resident" cat gets older. I think two neutered males are easiest to integrate, but male-female works well if the former is older and the latter three or four months old.
As for names, I strongly prefer real names, and not silly names or made-up phrases. Something you would have no compunction naming a child.
