The iPod app has to be on your iPad. It's a default app, and can not be deleted.
It is possible it is on another screen. Look between the top apps and the row of apps along the bottom of your screen. You should see a fain row of dots with a small magnifying glass icon to the left. However many dots you have is the number of screens you have, and each screen will have at least one icon on it.
To move between screens just swipe your finger from right to left across the screen, or vice versa if you want to go the other way. You should find your iPod app on one of the screens. It's a bright orange/yellow with a picture of a classic iPod in the middle.
The left most screen is a search screen. You can search your iPad for apps and other content that way. So, if you can't seem to find the iPod app the easy way, go to this screen and type iPod in the search bar. It should show up. You can launch it here, just to check things out, but you're going to want to find it and move it to a more convenient screen later.
To help you along the way a bit more I'm giving you a link to the iPad support site at Apple. You can download a PDF version of the iPad Users Guide from there. This is best done on a computer for now, but there is a way to load and read it on the iPad. Browsing through it should give a good overview of what and how things work on your iPad.

You can also get this manual through iBooks, which I highly recommend. Go to the Apps Store and download iBooks. It's free. When you have iBooks, open it and go to the iBooks Store in the app. Search for the iPad Users Guide and download it. It is also free.
