Personally I wouldn't go for Ubuntu if you just starting out. When i started with linux i tried out a few distros and eventually settled with Mandriva. I found this far easier to use than Ubuntu partially because the KDE desktop environment is very similar to windows amongst other things. I admit though that Ubuntu does have an astounding support network and i always end up with ubuntu results when i search Google.
Also, if you're just starting out, i highly reccomend
this book. It introduces you to working in bash and has helped me a great deal.
In addition, make sure you make a note of every piece of hardwre on your system as windows describes it (I assume you're running windows at the mo). It's a lot easier to troubleshoot unrecognised hardware when you know what it is supposed to be.
