Walkthrough for GT4

Does anyone happen to have a link to a walkthrough guide for progressing through GT4?

 

Check the stickied threads. There an incredible amount of information in them.

 

I checked all the stickies and the "read this before you ask" stuff. Found a walkthrough for GT3 did not find one for GT4 hence my question.
