I would say that recharge has always been and perhaps always will be the best friend of a fiery aura meleer. Sure, the attacks are plenty quick on their own, but one of the strongest tools in the natural arsenal of a fiery aura brute is healing flames. You may not admit it here, but I will honestly say that there have been times that healing flames being available just a second or two earlier may have made the difference between life and death. Having it up as quickly as possible makes a tremendous amount of sense to me. Therefore, I think you should strongly consider taking hasten for your build. Recharge is never a bad thing.
I also would suggest taking consume. Things may look ok just dealing with typical enemy groups at 25 or so, but when you reach lvl 50 and are having protracted battles with massive spawns and archvillains can be taxing on your blue bar. I loathe the idea of being completely dependent on (and an annoyance of) a good kin by spamming for SB all the time. Obviously, I would fire consume off if I need to pick up some endurance points, but I also use it to grab a bit of aggro if it spills off onto a nearby squishie.
When you start swimming with IOs and all, I hope you look into using IOs to plug the KB hole and respeccing out of Acro. I find that my 50 build for /FA does well using IOs to cover KB and it is completely absent of Acro.
Currently, I don't have BoF in my build, and a lot of people find it to be skippable. I do enjoy the animation of the power though, and it always helps to have cones/AoEs in your build. Some people claim it is too difficult to "line up" mobs to burn with BoF, but I find that just by not using it as an opener, you can avoid that issue. After all, just standing any place for a moment with Blazing aura running, you are going to have a few mobs swarming over you.
If there is something else to build for with IOs, defense is a great thing. It can be easily had and with IOs that aren't too expensive. Just remember things may be a little rough until you get all of the pieces you really want to have in your build, you may even use dual builds to work on your partially IOd build until you have all of the pieces in place, and use an SO build for normal duty.
I won't post a build using mids, and I hope you find this helpful.
Words to the wise aren't necessary- it's the stupid ones that need them.

I recently got my fire/fire brute to 25, and I was curious to know what the best route to go would be for fire/fire. The recharge times on the powers are quite quick, so I am thinking that hasten isn't necessary, same goes for recharge IO sets. I'm looking to survive while still putting out damage, and my build so far has only left out consume, taunt, and breath of fire. I have tough, acro, stamina, and electric fences for Burn. Any ideas? I'm looking for a build or two for mids' if anyone is willing to throw me one. I'm not sure how to go about getting IO's for things other than Rchg. Should I go defense, regen, more resistance? Any help would be appreciated.
