Hi Vanessa and
On the first question.....I'm no expert on the matter because I have only been hybridizing since 2011, however I would say yes it is possible to get a dormant from 2 evergreens. You have to remember that these plants go back 10 generations (maybe more) so you have to look back at what the parentage holds. And then to me it's still no guarantee because you really may not know what is lying dormant in those genes that will pop up down the road.
Look at ICICLES for example, the 2 parents are evergreens but the plant itself is dormant. If you look back at the parents of ICICLES they have dormant in their background.
Second question is everyone I know of lets the seedling go ahead and bloom whenever it gets ready to. Here we can bloom a seedling in under a year but there are some zones that have to wait 2-3 years to see a bloom. Plants tends to know when it is old enough/mature enough to bloom so I see no reason to pinch the blooms off.
