The learning curve on Access is very steep. If you jump into too quickly, you can easily program yourself into a corner.
My first database project in Access was an utter disaster, and after 3 months I had to scrap what I had and start over.
I HIGHLY recommend that in addition to learning the ins-and-outs of Access, make sure you have a good understanding of the aspects of Relational Databases, especially the Rules of Normalization.
If you do not set up your data tables according to the Rules of Normalization, you are going to eventually find that seemingly simple tasks become difficult and cumbersome and/or the database won't be very dynamic.
