regardless of what school of buddhism you chose to follow(or in the case of some western practitioners,trying to follow them all)i think a good overview of buddhism is"old paths,white clouds"by tich naht hahn.then go deeper into the philosophy if you feel the need to do so.there are quite a few good books out there(and alot of garbadge),so be careful.alot of the current writings on zen are misleading concerning zen,and taoism.
i have several books i use for reference,and a few more i would like to get someday.i wish you well on your journey.
