I used the GameFAQ guide, seemed pretty good.http://www.gamefaqs.com/xbox360/943397-deadly-premonition/fa...
A few small tips about the game in general.
Most parts can be skipped by pressing the 'start' button, that includes cut-scenes (e.g getting in/out of car), speech, typewriter effect text, the pop-up screen when you pick something up, etc. Though I don't suggest skipping cut-scenes or story related stuff as it would seriously take away much of the enjoyment from the game.
The typewriter effect text can be speed up by holding down B button.
You can move through doors slightly faster if you sprint into and whilst sprinting 'open' them. it avoids the lengthy 'cautious' animation, playing a faster one.
