Fields to index chapters, figures and plates.

I know there's a way to get Word to auto generate TOC but I am struggling to get my head round it. I am using 2007.
I need at the front of my document
a) a table of contents showing chapter titles
b) a table of contents showing figures
c) a table of contents showing plates

and I need to auto number, with sub numbers i.e 1.2 (only 2 levels), chapters
and to auto number figures (drawings) and plates(photos)

and then to be able to add the references to the figures and plates into the text.

Can anyone help an old man having a senior moment?

Thanks

Allan
