#3 Apply force when curing. This could be hard to do depending on the location of the bulkhead. I have used tiny screws to attach the former to the fuselage, and cover the holes later.
#4 Make nice glue fillet all around
That being said, 30 min epoxy should work fine. I use Hysol E20HP a lot too, it is great! If your fuselage is Polyester, Hysol works better.

Iots of good information in this thread, but I think Falcons comment above is the most relevant..
A well prepared joint using an average quality glue, will be much stronger than a poorly prepared join using a high quality glue. Like all things in life preparation is everything.
I use Hysol with good results., but I also use West epoxy, mixed with glue powder, for a lot of critical glue jobs. I could not tell you which is stronger, but a well fitted West Epoxy/powder joint is damn hard to remove.. The ply will break out before the glue lets go..
