For learning, yes, avoid libraries. Especially for something as conceptually simple as AJAX, forcing yourself to learn how the browser can be used ‘raw’ will benefit you immensely later on, even if you are using a library to take care of the drudgery and abstract away browser differences.
Once you have a solid understanding of how it works though, use a library, if for no other reason than spending time working around subtle browser differences is a waste. Better yet though, spending some time reading through the source of jQuery and others will give you insight into what well-written JavaScript looks like – and that in turn will benefit the code you do write!
