You could lager if you want. I think it would help smooth out the beer early and you could probably drink it sooner, although I'd look at lagering it for 4-6 weeks, if you can. On the other hand, you'll drop out a lot of yeast so carbonation will occur at a slower rate. You may be happier bottling after 2-3 weeks and then after the bottles have carbonated you can stick them in the garage to lager over the winter, as long as the bottles won't freeze.
I would bottle and then cold condition them, it will just make the carbonation process go easier with less issues.
This. Cold condition after you are carbonated. It will slow the staling reactions, and still provide "lagering" time. The longer you can wait the better. I would store all of the beer in the garage, and just a few in the fridge unless you have a lot of space. Conditioning is really important with this style IMO.
yso, I think the lower-gravity versions of the style come into their own a lot quicker. I think 2 weeks in the cold will be fine.
