One feat you should check out is Deadeye Shot from PHB2. It lets you ready an attack to shoot an enemy when an ally hits him, and when it occurs, the target loses his Dex bonus against your attack. The feat would allow you to sneak attack at range and would also work well with the Order of the Bow Initiate (since the PrC lets you do extra attack on a shot made as a standard action).
