[Morgeruat]

the number to the right of your strength/dex score is your modifier, both to hit/damage (yes it's the same bonus now) and for any abilities that use that ability, say you have a 16 dex (+3 mod I think) then with a bow you would receive a bonus of +3 to hit, if you have a 17 strength (+3 still) you get get +3 to hit and +3 to damage with your weapon, unless you're using a light weapon and have weapon expertise (in which case you use your dex bonus instead)

Ranged weapons don't use the strength mod for damage unless you have a composite bow (long or short) and I think hurlded misile weapons (throwing axes, shuriken etc.) use str for damage bonus
