Hi Karyn.
Well I've been in this situation more times than I want to admit to. LOL! Granted, allowing the room to breathe with the drums can be a good thing...but it can also be a bad thing if you're stuck with the print and it's over-bearing. In today's times we rarely hear a drum kit with the room ambience of a warehouse, so I'd definitely control the room.
For what it's worth, here's what I do in this situation. The first thing I do is lay some carpet down where the drum kit will be set up. I then tack or tape the wall behind the drum kit IF possible. I know, you may not have any walls depending on the warehouse and how it's structured. From there I build an isolation booth around the kit using quilt racks/blanket racks like what you see below.

LOL! But anyway, this little virtual booth of blankets or carpeting can really make a world of difference in controlling the room. Anything that you can put around the drum kit to stop the huge room artifacts will help especially since you are close mic'ing.
The good thing is, Ed has volunteered a great service and that is, Drumagog...which is spectacular and should be in every engineers tool box by default. Yeah Ed, it will work on jazz, World beat and even works live in real time. I actually did a demonstration with it for a client one time creating an entire drum sound using my mouth beat box'ing into a mic and then adding drum samples to what I mouthed. The end result was an absolutely perfect drum kit.
So this is a really great alternative too Karyn in the event you just want a bit more reinforcement or you have some problem areas. If you have problem areas, all you'll need to do is cut the problem clips up tight so that all that is heard are the hits that you would want replaced. If you have a problem with hats Ed, due to how expressive they can be, you can always cut the track up and put the open hats on their own track and just use Drumagog open hat samples there.
But seriously Karyn, keep Drumagog in your thoughts. Just about every studio known to man is using something like it or running midi triggers (D-Drum) on their kits as a safety net. Drumagog will work with midi stuff too although they have always had a problem with it in Sonar only. There are work-arounds for this though. But since you won't be running midi, you won't have a need for that feature. Another form of correction if need be is to use Audio Snap to turn drum beats into midi so that you can use SD3, BFD, Superior, Steven Slate etc....so you have a load of options at your disposal.
I recently did some work for guitar virtuoso Greg Howe to where we used Drumagog all over the album he produced. Anyone knowing of Greg's work knows he always has a fierce drummer on board. It worked like a charm with my own custom samples as well as the samples you can buy for it. If you have lots of bleed, eq the sound to remove as much of the bleed as possible and then gate it. Then run Drumagog on the track and it will only trigger the hits. It's truly an amazing piece of kit. :) I hope this helps...best of luck Karyn. :)
