Restoring Macbook, but only need to save a few things

[Fainer]

I recently got a new iMac and used Time Machine to transfer everything over from my white Macbook. Piece of cake.

My Macbook is now being used mainly for one specific task: teaching teenagers in youth group. I extensively use Keynote and iTunes. Occasionaly Garageband. I dont need any other files on it. It has also been running quite slow with occasional lock ups (last night for instance during a lesson). So I think that wiping everything off and restoring it to factory would help. But I do not need to restore everything from a Time Machine backup, just iTunes. I do not want to lose my music/media from that. I also want to make sure I keep Keynote and Garageband. I dont care about keeping anything else. What would be the best way to do this? Thanks so much!

(I have the white Macbook, not with the 1 clickable mouse button. It has a 500 GB HD and 4 GB of RAM. I also have Lion installed.)

One option is to configure time-machine to only backup the files you care about.
Which sounds like your iTunes library and your applications.
Then do a fresh install and restore from the (now slimmed down) backup.

The real question is why is your Mac slowing down.

No idea. Except that it is pretty old (5+ years) and I just assume it is showing its age. That is why I am hoping that after wiping it clean and just installing the music and apps I need, it will run better....hopefully.
