you will need a itunes account and then go to the app store. search for skype and install. it will prompt you to create a skype account if you do not already have one.

I don't know about Yahoo messenger, but you can certainly download Skype onto your iPad. Search for 'Skype' in the App Store, and you'll be able to download it free. There is no iPad specific version of Skype, but the iPhone one runs and works fine.
As for Yahoo messenger - do the same thing, run a search in the App Store to see if you can get it for iPad. If not, see if you can do it via the web - Safari on iPad is a very capable browser, much more so than Internet Explorer, at least.
Hope that helps!
