Ok, simple question. What steps do I have to follow to get both installed? 
I'm a complete Linux newbie and need very straight forward, step-by-step 
instructions as I'm still learning. Seems that everytime I think I 
understand something, a new switch gets thrown in and I have no idea what it 
does. I'm in the middle of RTFM... I'm getting there =) Thanks all!

Brian
