A lot of your questions can be answered by yourself if you look through some of the past posts in this forum which is for professional pilots.
If you read the 'sticky' above that says 'Read before posting' you will find that most of the questions will have already been asked before. There is also an excellent search facility.
Some of the questions that you ask are very specific to your country and therefore they are unlikely to get a full answer - unless you are lucky!
I would only say that at the moment the aviation industry as a whole is suffering and there is very little recruitment going on. A lot of airlines have had to make pilots redundant and consequently there are many very experienced pilots trying to get the few jobs that come up. Eventually things will pick up and those less fortunate pilots will find jobs and the recruitment will start again.
However I would not advise anyone to embark on a very expensive programme until you see that pilots are being re-employed once again. That would be the time to take the plunge but in the meantime keep watching these forums and you will soon develop a 'feel' for how things are going.
