All those programs cost a fortune. If you want a job in web design then they are a worth while investment but for small time stuff, it's not worth it.

You can use freeware programs like Photofiltre and Notepad and OpenOffice to do basically everything you need to do. Even Audacity if you want to do audio work.

Start of small and when you know you are serious, step up with all the skills you have obtained and then get into these other programs.
