Does a character get all of the benefits of Blind Fight when using a ranged weapon?
It depends on how you play your archer.
I tend to play purely artillery types using meat shields and traps to prevent getting mobbed so, though I do benefit from the re-roll in those cases, since my PC remains well out of melee range at all times, BF's AC and attack issues never factor in.
However, for those who employ extensive use of PBS, then ~yes~... the full Monty of BF effects applies.
Zen archers get a slightly less BF advantage since flat-footedness is not near as significant as is with a dexer archer.
