Excellent question. To start with cleaning, go to your web browser and select "empty cache" from the file menu above. If you use Safari, it's located under the Safari tab. Defragmenting is a whole other thing. The truth is, Macs don't really need defragmenting.
Watch this video. It explains a lot.
Their file system works differently. If your Mac is running slow, first try to reset your PRAM. Just google it. After this, if it's still being slow (and if you've had it for a while, I know what you mean, OS X does slow down): my top recommendation would be:
Back up all your data onto an external drive Boot off of your factory restore (OS X install DVD) Use disk utility to format your MBP's hard drive Clean reinstall OS X Restore your data and it will write it to the hard drive neatly
You'll be amazed how fast Macs are with a clean install. Amazing.
This isn't windows, so you won't need to install drivers or other messy stuff. Just make sure you have all of your software DVD's if you decide to do this.
Hope this helps.

Go into Disk Utility and click on your hard drive click "Repair Disk Permissions". Then after that it should work a little bit better depending on how old your computer is.

Excellent suggestions already. I'd like to add an app I've found awesome for cleaning up and reducing wasted space on my Macs -- Clean My Mac by MacPaw software. It's commercial software but you can take it out for a test drive before committing to buying a license. Highly recommended.

To run some more hardcore and detailed maintenance tasks, download the free OnyX. Uninstall unused applications. Over the course of time, you may have cluttered your Mac OS X hard drive with various software installations. Click "Applications" in your dock and drag any unused programs to the trash bin. Empty the trash.
