configuring the keyboard broadcaster aka the keyclone and rest of the programs you mention above, as well as getting some suitable macro's together.
as well as getting past the first few hours and correcting any problems or lack of configurations that you have missed the first couple of evenings of boxing is not a picknic

hang in there, like the person above me said, start with someting really easy and simple. and take simple small babystep from there on. check the wiki, and use the search function and go trougth
post other have created before you, you should find problems and situatiosn closely to your own and use the feedback and information in those treads to find solutions to atleast some of the problems
that are giving you a headeache and pain now

when you have gotten yourself a prober configuration and macro's and gotten a hang of the boxing part you will spend a lot of hours opon hours enjoying the multiboxing experience. the headeache from the
first few evenings are well worth it.
