New Guy wanting help with HP dv2419

[xflipzpridex]

Hey there So I basically just wanted to ask a few questions.
So I have a HP dv2419us laptop and I love it. However it came with Vista, and I seem to prefer Mac OSX to Vista. Also, I'm still in high school, and I have been using Windows all my life, and I want to learn how to use a mac so when I get one for college, I won't be completely confused with how it works. So I just bought this laptop a year or two ago, so I don't want to buy a macbook, because it's soooo expensive. So I was just wondering if my laptop could handle dual booting Mac OSX and Vista? Here are my laptop specs.:

HP Pavilion dv2419us
Windows Vista Home Premium
Processor: AMD Turion(tm) 64 X2 (2 CPUs), ~1.8Hz
Memory: 958MB RAM
Hard Drive: Free space: 41.8 GB (I can get a USB hard drive if this is too little)

If my laptop can handle it, I was wondering which guides would tell me how step by step, since of course, I'm a beginner.

Thanks so much for your help
