How can I update shipping rates and add surcharges on UPS?

Hello, 

 
I have a couple of questions. First, are the shipping rates automatically increased and updated with UPS to reflect their increases? The shipping label I printed was much lower than the price of bringing the package to the UPS building to ship. I'm guessing this may also have to do with the discount price from printing our own labels? 
Also, is there a way to add surcharges or additional charges and have these show up for customers to see? 
 
Thank you.
