Well I can tell you what I use when I'm not being a lazy bard. It's not perf but... it works for now.

WM prepull
IR + B4B + RS + HS (yes all at once)
Bloodletter
Windbite
Venomous Bite
Barrage + Empyreal Arrow
Straight Shot
Heavy Shot
right before the DOTs all fall off I use Iron Jaws for a bit more length to the buffed DOTs.

then it's wait for SS/BL/EA procs.
In there somewhere I cast Flaming Arrow, usually after the first SS. I tend to forget though (bad bard), but you should do it.
I only use Barrage w/EA...just, if you were wondering to do that or not...

EDIT: ah yes I just keep WM on for most of the time. I have Feint CC in case I need to move for a GCD or two... anything longer than that and I turn it off to run around or whatever happened, then turn it back on.
Some people like to turn off WM and stance dance between Empyreal Arrows but I haven't done a proper test of that myself yet...honestly I feel like it would be negligible with the amount of effort but hey, whatever.
