Basically you connect the iPad to your computer and launch iTunes. Click on the iPad name under the devices heading on the left side of the iTunes window and you should be notified by iTunes that there is an update available for the iPad. If iTunes doesn't do it automatically, you can click on the Check for Update button in the Summary Tab in iTunes.
Read this first. It explains it clearly.

You need to connect to iTunes using the supplied dock connector to usb cable. You will see the iPad appear under devices on the right hand side. Select it and you can click on update.
If you have never connected or done a sync before you will need to transfer content to your computer first. If you attempt a sync for the first time the iPad will be erased. See below before you update in this case.
For iTunes content - transfer purchases
If you have content not bought from iTunes you will need to search for a 3rd party program to transfer them.
To backup your iPad's data, right click on the iPad (under devices) and select backup

Go to the App Store on the Ipad
Then on the buttom right corner, click updates.
When you have a notification number next to the app called App Store that means that number of notifications need to be updated.

That's how one updates apps, not the OS

If you are referring to updating directly that requires IOS 5, which the OP doesn't have
