No problem... that's why the forum is here. I'm sure most of the people here have been in your shoes at the beginning... I was simply born knowing everything so I've no idea what it must be like.
Seriously though, welcome to the forum... go buy a copy of the TSRM (Toyota Service and Repair Manual) for the MKIII and skim through the online copy to learn the layout. The online one is for a '91 so there are some differences but most of it is the same.
