I'd hardly call 31 days "quick turnaround". Fastest I've ever done is 9 days grain-to-glass, on a split batch (half APA, half IPA). The only difference between batches was the yeast strain (Cal Ale for the IPA and San Diego Super Yeast for the APA) and the hopping (I did a whirlpool for the IPA and a larger dry hop). The APA turned out pretty well (won a silver medal) and the IPA was a terrible diacetyl bomb that I ended up dumping.
All of that to say, yeast strain is important, but 31 days should be plenty for any ale yeast. If you had a shorter time frame, I would look at something other than US-05. I have had diacetyl issues with that yeast as well when I didn't give it time to clean up. But as it stands, I think you will be fine.
To answer your other questions, I assume that you mean "bulk fermentation" to include all time spent in the fermenter, which includes letting the yeast clean up. And I assume "conditioning" is after you have removed it from the (primary) fermenter. Is that accurate? If so, fermentation will have a much greater impact. Leave the beer on the yeast until it is ready for packaging.
EDIT: The IPA I mentioned above also had some cane sugar added to it that the APA didn't have.
