I think I may have tweaked something in my lower back. It starts feeling better, then I deadlift, then I'm crippled again. So, I've called a deadlift moratorium for 2 weeks to let it fully heal up. However, I'd like to avoid regressing and hoped there might be some exercises I can do in the meantime to keep moving forward without aggravating the back.
Don't risk jacking up your back. Back injuries are the worst and you'd be smart to take some time off to avoid more serious injuries in the future. I realize that a lot of people have the sentiment that "letting an injury heal is for pussies" but whatever ...
I'm sure you have some other weak points that aren't getting much attention -- maybe you should focus on those in the mean time
2 weeks off deadlifting will be good for you. Typically before a meet, I don't pull for two weeks and the day of the meet, I kick ass. I think that's pretty typical. All to say, just do something else and don't worry about anything having any carry over with a substitute lift. Just try something different and have a bit of fun with it.
Find yourself a good chiropractor. One that treats athletes. He should be able to correct your problems so that you will be able to train w/o repeatedly tweaking your back-provided your techinique is sound.
On your DL day, instead of dl'ing, focus more on mobility and flexibility and anything that will help protect your back in the future. Open up your hips, wake up some sleepy hamstrings, work on your ab/ad-ductors, do some single leg work to balance out the strength between your two legs, and so on.
Whatever you can do to not aggravate your back is good. I hurt my back a few weeks ago and spent some time working on my conditioning. I doubt you have access to a belt squat machine but that might be a good alternative.
If you're weak off the floor you can do some single leg or close stance leg movements
