BARD resource?

If you're going to use that macro, Heavy Shot goes first.

Agree 100%. ME & BL are off the GCD skills, so should be used between GCD's to maximize dps. Placing HS lowest in priority would cause non-GCD skills to be used first, delaying your GCD usage => reducing dps

Since Straight Shot, Windbite, and Venomous Bite all have slightly overlapping durations, is there any kind of rotation for bard that optimizes their uptime without clipping or letting them drop?

Nope. Just make sure you have SS up when you apply them. Getting Straighter Shot procs from HS usage makes the overlap issue moot , as you'll be resetting the SS buff when you can. Use WB prior to VB in your rotation; for any situation that warrants putting both dots up, WB first is the better choice.
