Answer - I think it is an eminently sensible plan. Why commit yourself to anything before taking the time to find out if it is right for you and what is the best way for you to approach it.
I'd make sure that you are reading a wide range of books from different perspectives and not just following one single book/way/guide/path. I see too many witches who read one book and take it to be (ahem) gospel truth. Chances are that the path you eventually choose to walk will be a blend of the practises and beliefs that feel right to you and by widening the scope of your reading you will encounter many different ideas that you will accept/reject/develop as you find the way that is right for you.
I would however add that the path of a witch is not simply one of study. There is no reason why someone new to witchcraft should have to read every book under the sun until she gets her hands dirty. I'd certainly start getting stuck into some practical work as well. Not necessarily spells but possibly learning about some plant lore and growing one or two things to build up your relationship with the natural world. Or some basic craft work, learn how to work your intent into objects and express yourself through your own creativity.
Study with an open mind and don't be afraid to have a go, that's my advice to you.
