The analyses of a text

Someone tries to kill the protagonist on April 30 every year.

I was not jangling with strange apprehension, as I had been on that April 30 three years ago when I'd awakened with a headache and a premonition, thrown open the windows, and gone to the kitchen to discover all of the gas burners turned on and flameless. No. It wasn't even like the April 30 two years ago in the other apartment when I awoke before dawn to faint smell of smoke to learn that the place was on fire. Still, I stayed out of direct line of the light fixtures in case the bulbs were filled with something flammable.

I'd like to know if I can rephrase "thrown open the windows" as "thrown the windows open."
I'd like to know "when I awoke" and "to learn" modify "the April 30 two years ago."
And I 'd like to know what "still" means here."
Thank you in advance for your help.
