For picture guides to dish setup with/without diseqc motor:
For a "very basic" introduction, see:

For an introduction to setting up a diseqc motor, see:

(warning, this above site is USA specific, so ignore any actual figures given!).

Lastly, here's an excellent download from satcure, loads of pictures, then you probably won't need a book or video. But - warning - this pdf file is BIG, you must have a wideband connection!

If you only want a fixed dish, with 1 lnb, for 1 satellite, then just work out very roughly where the sat should be - using one of the web "calucuators" - aim the dish roughly, then find the actual signal using a "sat bleeper".
For a fixed dish with monobloc twin horn lnb (for Hotbird/Astra1 combined), it's much the same, except there's a built in diseqc switch. Once either lnb horn is positioned - on the correct satellite - the other should automatically be ok.
For a fixed dish with 3 lnbs on a bracket (Astra2/Astra1/Hotbird), things get a bit more fiddly, you might then want a "Digisat Pro".
(sorry folks, I realise these links all point outside satellites.co.uk, but Nick1 seemed to be after pictorial type info, so I was trying to be helpful. However, obviously there's the above links pages, with loadsa stuff in them!).
