Without modification to frame and/or forks, then this is about all you can do to make it lower.


The red line represents the ground. The green line under the front 'lucky seven' sprocket is the height or clearance.




Remove the spring from the crown set and get a shorter bolt fastener, then secure the crown and bushing directly to the L bracket.
This will make steering limited but will get your bicycle lower. See the green line that is now shorter.




The squeaky noise is difficult to detect in your video, but I think it is the spring front fork set that is metal against metal. This is normal unless you pack all friction points with grease.  

you can purchase a longer down crown which will enable to bike to become alot lower, the only cost about $30 australian
