Welcome to the forum where there are a great number of experienced commercial pilots and even more folk like yourself.
One thing you will find is that nearly all the questions that you want to ask will already have been asked - and answered - many times before in other threads.
Could I ask you to carry out some research using the 'Search' function? You will also see the 'Stickies' on the initial forum page that contain a wealth of information.
