Ok mate that's the right way!
But be sure if the laptop you will buy has at least 520mb RAM (I would recomend even more)
Now let's talk about monitors, have you ever though about that? M-Audio has pretty good monitors at a very afordable price!
You might be interested to get a mixer with more channels, this Behringer's one is pretty good (for recording) but I would also recommend you to get one with more channels because if in the future you wish to record something using more tracks.
Have you tought of what software are you going to use? And what about drum machines?
YOU ARE ALWAYS WELCOME!
