Nah, man I'm nothing special. With that one I got lucky there was a guitar pro file with the bass already tabbed out and sounded really accurate.
As for tips, there's already a couple really well documented tips on the forums already by firekorn, iminashi, and Berneer.
As for my tips, just practice listening to the songs and listening for the particular instrument. And practice with EoF (Editor on Fire). I've made a couple CDLCs of my own and started real small, but I've done musical charting in the past both by hand and with software, so probably don't take my path as "I can do this just as easy!" cause it might be a slightly different journey =p
Really, jump into EOF with a band you like, if you have Guitar Pro (I really recommend it) you can find stuff people may have already tabbed out to make the EoF part easy, and fiddle with stuff. Break things, make mistakes, and learn about what's going on
