As for moving to secondary, IMO you are too late to use a secondary fermentation schedule. Using an ambitious FG of 1.015 you have already chewed through about 85% of your fermentables. If you transferred now you would not bring enough yeast to finish and condition the beer.
Give the beer enough time on the cake to fully condition; I think 3 weeks is good but a month may not be a bad idea.
After that, purge your bright tanks (carboys) with CO2, and transfer in being careful about air contact. Beers that will be subjected to age have a higher likelihood of oxidation problems.
The beer that is getting oaked should have a third vessel to spend its bulk aging time in.
Update: I just racked it to two five gallon secondaries. I am tentatively planning on two weeks in there. then one is going to bottle and the other will go to tertiary for an oaking session for plus or minus a week, then bottled when it tastes right.
