I love lagers! I hate lagering. It's a game of patience that I don't have. I like how I can turn an ale around in two weeks, but lagers take at least two months or more.
My general lager schedule goes something like this:
Make wort.
Chill wort to pitch temp. For me, this is the high side of the lager yeast ideal temp (high ideal for lager, low ideal for ale is my thing) probably around 58°.
Ferment for two weeks.
Transfer to secondary (the only time I ever do)
Slowly drop temp. about 2° - 3° per day until it gets down to around 34°.
This is where the patience comes in - forget about it for at least a month. The longer, the better, but I normally don't wait longer.
About 3 days before kegging I will add gelatin - 1/4 tsp/5 gallons dissolved.

As far as room-temp fermentation - I have done that too. No lagering, of course, but it turns out really good. Definitely a different flavor, but not in a bad way. Kinda hard to explain. The best way to experience it is to make a lager, bottle a couple to put in the fridge (more lagering), then make a room-temp version of the same recipe. Now you can compare side by side.
