I always let my ales like this go two weeks, just to be safe. If you go shorter periods before bottling, I'd recommend checking the final gravity over a few days to make sure it's really done. A low-gravity mild should ferment out quickly, given a good pitching rate, but I always play on the safe side.
A mild won't keep as long has a higher-gravity ale, but it will still last a few months, easily. Unless it is really good, then it likely won't last that long anyway!
I don't bother with cold-crashing ales like this, especially if the point is to let them bottle condition. And unless they are very light in color, that perfect clarity isn't a big deal anyway.
Nice to see another mild fan out there. Cheers!
