Uncertainties and data loggers

I have my evaluative tomorrow and there a few things I am unsure of.

How many sig figs/dp do you get a percentage uncertainity to?

Also for one of the limitations i am thinking of using a data logger. I am not fully sure on how they work. If someone could explain that it would he appreciated. Do you just hook it up to excel and get results lol?

The only other limitation I can think of was wires in contact together as we sorted twisted two capacitors together. Is there a way you can improve that?

Thanks
