How to change account info and hook up iCloud to my mac?

My dad bought a laptop (macbook model A1342) a few years ago and now it's mine. However, the account is still under his name and all my files and bookmarks are on this account. Is there any way for me to change it so that it's under my name and email address?

Also the Mail application has his MobileMe and RSS accounts. I was able to login to my own account on it but is there a way to get rid of his accounts?

I have an iPhone that used to be his too, but now I have my own Apple ID and it's under my account. I'd like to hook up iCloud to get stuff from my phone to my mac, such as the Find My iPhone app, but I can't find iCloud on my computer.

Good iPhone adventure games?

I'm looking for some good adventure games for the iPhone. I don't mean games that have a bunch of levels where you do the same thing every time plus a story, like Angry Birds or Cut The Rope. I'm looking for games that can be side-scrollers, and might or might not play like Super Mario Bros. They don't have to, but I'm just giving an example. I have played games like LostWinds 1 and 2, Paper Monsters, Swordigo, Age of Zombies, Buck And The Coin of Destiny, etc. It doesn't really matter the cost, as like as it's not something like a whole eight dollars. If you can name a few, then that would be great.
