I'm sorry but you can't call this a "speed run" when using speed up tool and using game time as measure. When you use speed up, your game time will actually be halved. Not to mention that breaks aren't allowed in speed running.
In the end it looks like you aren't prepared at all when you're asking people for suggestions on how to do something. If you ever want to do a proper speed run you will need at least months to prepare for everything, sometimes even years.
Anyway good luck with this
