for beers that dont require secondary-ing (like hefeweisens, other cloudy beers, or primarys that dont have a lot of junk in them), i normally let the fermentation finish and then throw it in a keg. hook it up to CO2 and leave it at room temp for 1-4 weeks (normally around 2). then chill it for 2 weeks under gas to carbonate.
as long as fermentation is finished, you can immediately hook it up to gas. some people dont like to age or condition beer under pressure, but CO2 prevents a lot of bacterial growth. also some of my corney keg lids need a shot of pressure to seal completely. a leaky lid means there is a hole that germs and oxygen can get into. at minimum you should flush the headspace with CO2 a few times after filling a keg, even if you dont need pressure to seal your lid.
if you only put a little pressure into it to seal the lid, that gas will disolve into the beer and drop the pressure, which can then let the lid continue to leak, then all your CO2 is gone. this is why i keep mine hooked up to gas whenever not fully carbonated.
