Absolutely, your best place to start is the wiki (linked above). Multiboxing requires a major change in the way you think about engagements, so understanding the underpinnings like following, movement, targeting and assist macros should be your first focus area.

Also, don't take it too hard if you ask vague questions and get a little flamed for it. Just go try some things, read up, do some more experimentation and then come back with specific questions. At that point, I'm sure we'll be more than happy to help you through the particulars of your setup. GL!
