Welcome to the Wannabee forums where you will find any number of people willing to help you get your foot on the first rung of the ladder.
However he questions you ask have been asked - and answered- many times before recently so may I suggest you use the search function and spend a couple of hours reading through some of the threads. This will not only answer some of your concerns but also give you a good insight into the commercial aviation industry.. It will also show you the problems the industry is trying to cope with and the large numbers of pilots trying to find employment.
I wish you success
