The creatine won't have that dramatic of an effect right away.
Good progress. On the power cleans I've noticed I get sloppy as it gets heavy as well. The best thing I've done is lengthen my rest a little and make sure I get a good starting position before every lift rather than trying to rush each rep per set. A typical set will look like:
Setup the lift, pull, catch, stand up, drop the weight
reset the bar
It might take a few seconds longer but I'm rather do it the right way than try to rush my set along.
