Talk about jumping straight in!
I hope you like mathematics, because you are going to be doing a fair few subjects that requires it.
General programming & scripting doesn't involve advanced math so you could look at taking a Bachelor of IT instead. It will still teach you about programming, scripting, the software development life cycle (probably as an elective) and business processing and analysis.
Computer Science is definitely a more theoretical (scientific) approach to solving advanced/complicated problems. While the IT degress are more applied and broad.
I have no idea about your capability, I just wanted to let you know that if you just want to do everyday programming grunt work, then CS is very much overkill.
In the mean time, maybe consider looking at
code academy for some free programming lessons or computer science on the
Khan academy site to get a feel of what it is you that appeals to you most.
Good luck with it.
