There are various series of tutorials out there. Like I said, you might have to dig a little to find what you want.
Once you finish one, you can search for other topics, if that is the way you choose to go.
Note that there is a lot to learn in Access. If you think you are going to be able to learn it in just a few hours, you are mistaken.
Personally, I would not recommend trying to learn it solely from tutorials, unless you find a good series that is structured enough to go from start to end.
I learned initially by grabbing Microsoft Access Step-by-Step book, which comes with a DVD. Once you progress through that, they you can start looking into Access VBA.
Actually, if you are not familiar with the concepts of Relational Databases and the Rules of Normalization, I actually recommend starting there before even getting in to Access, especially if you are going to be doing any sort of database design. Trying to design anything other than a simple database without having a good understanding of those concepts will be very frustrated (I learned that lesson the hard way myself).
