You used to be able to get the incline loop formula from CoasterCandy, but since that's gone I doubt you'll be able to get it. As for the rest of the tools, you can find them here:

If you're going to make an incline loop MACchiato's way, I'd reccomend using the 'ampl' feature to get the incline and rotating it 90* in the purg. It means there won't be a slight lateral jerk leading into the loop.
