To know how likely you are to hit in combat (and conversely how likely monsters are to hit you), see the Armor Class page.  The Weapons page will tell you all about the different kinds of weapons in terms of damage and other properties, but note that for ranges of weapons you may need to look elsewhere (for instance, the range of your bow is actually defined by the type of Arrow, it would seem, and most objects of reasonable throwing weight seem to have similar ranges as arrows).
