I'll answer your first question about scaling--that's the easy one. The answer is yes, you can scale and plant them directly in the garden, BUT YOU SHOULDN'T. The reasons you should not are that you lose environment control and your bulblet yield and bulblet survival rate will be much, much lower. If you spend big bucks for a nice lily and you really, really like it, then take the time and do it right and you will be happier in the end. Four, five or six scales is all you really need to get several baby bulblets started and it won't hurt the mother bulb at all. Scaling the mother bulb more than half way results in a smaller plant the following year but will recover nicely the second year.
Scales of several types of modern day commercial lilies taken in the Spring can be potted up directly out of incubation because they've already been chilled at the grower/supply source. Trumpets are kind of an exception in that they can be be potted up directly in the Fall as well without a chill.
Again,
