How do I start with these stuffs?

I am a 22 yrs computer engineering student and have really cool interest in programming. But yet haven't done anything more than college little crappy projects. I need some guide if you guys could provide how I could start with. I have like 10's of ideas on my mind through which I think I can make real money and reach somewhere recognizable. I think my self as an entrepreneur in making. I am little familiar with stuffs like php/mysql, html/css, c/c++, CMS like wordpress, OOP concepts but not very much. May be I want to go on the web stuffs, and definitely I am an opensource lover. I would be really glad to see some suggestions.
