Help me getting started with 2 accounts in WoW

Ok im a complete newbie at multiboxing but i finally got my eyes open about this and i want to try it out.

Luckily i have 2 computers, (actually 3 but my bro's using the 3rd)

1 laptop (core duo processors with 2gigs of ram and a 17'' widescr) and 1 of the ''big guys'' (1gig of ram but better videocard and also duo processors, including monitor 19'') I also have a Logitech G15 keyboard since I've heard it should help out with macro's and stuff.

Alright now i have seen your guides on how to get started but it all confused me pretty darn much i have to say (not blaming you) im just a really big newbie at this i guess :)

I would like your advices on wich computer i should run WoW on mainly and how to configure it using 2 accounts.

And how do i actually use 1 keyboard and mouse on 2 computers? Do i have to get a USB hub or anything? :S

And how to get started step by step cause im a big newbie.

Hope you guys up for helping a bit. :) Thanks alot.

Btw i just downloaded the AutoHotKey for the future when i get on with this, so dont expect me using the other key software because i cant pay for it im sorry :(
