Mac Book - help?

I just bought an Macbook and i'm REALLY stupid when it comes to computers, let alone a laptop.

I bought an apple protection and the "iwork" program. With it, came the Macbook OSX CD - Do i need to install that again?

and how does the "iwork" CD go? Is the installation hard?

I also bought a wireless mouse...help!

(i already got the whole internet thing fixed, so i'm good to go with that)

THANKS :)

Mac OS X comes preinstalled on your Mac. Apple gives you the CD just in case something goes wrong. Keep the CD in a safe place and don't worry about it. iWork free trial comes preinstalled on your Mac. Since you bought the program, just insert the disc. The iWork full version will install (telling you what to do each step of the way: its a breeze) and will delete the trial version.

Can't help you with the wireless mouse since you didn't give details.

In my opinion, you should just sell the MacBook and buy an HP or a Dell.
anybody who suggests that you get rid of your macbook for an hp is a narrow minded dolt. there is so much more one can do with a mac,

if you only use a computer to go online, then it doesn't matter which brand you use,but it seems like you will want to do some real work on your computer because you are interested in iwork.
