Here is my 100% Achievement guide with timestamps
Please note, because of the pathetic copyright in the game, there is no sound AND for an added bonus, youtube cut off my commentary from about 2:20:00 in or so, so for around another almost 2 hours you will hear nothing BUT i still have done it to the best i can in order to get it done quick, so just a few warnings for you there :)
Hope this helps :)
