First recommendation would be to totally farmiliarize yourself with as many of the systems, layout and features that you have onboard.
Grab a flashlight, and prepare to get a bit dirty, open every compartment, dive into the ER, bilge, etc and seek to understand what every bit onboard does.
Getting to know your boat and asking the questions here will help avoid any unpleasant situations in the future.
Ex: You stated you are waiting on the BIII drive. If in salt water, I will contribute watch for corrosion and be prepared to swap out you anodes regularly to protect that investment...
Bring the questions... We all would love to contribute from the security of our respective armchairs. 8-)
