Hi there! I am actually in exactly the same situation as you like for like. Also trying to information gather. Main thing I seem to learn is you can't cross bridge E before crossing bridge A, and planning crossing bridge B & C. Basically make the most of what you can in your current position, and try and maximise it every step of the way to make the next step somewhat less painful! Would be fab to be in touch and discuss any learnings on this situation! Comforting to know I am not the only person in this exact situation!
