Looking for some citrix guidance

Hey,
I've just started a new role today which will see me really heavily involved in Citrix Xenapp and Xendesktop. Any recommendations on good learning material? Particularly on Xendesktop because I've not worked with it before. Are the e-learning kits a good investment?
Thanks

I didn't use an e-learning kit so I can't comment on it.
