Setting Up UPS Shipping Module For Dropshipping

[Sounds]

Hi,

I have a scenario where we will be using 1 wholesaler from china for drop-shipping.
I'm not sure how to set up this default_ups module but I guess as some of the
products come from china, we should set the origin info for china. right?
What if we have more than 1 drop-shipper, what should we do?

Has anyone set up this module for drop-shipping services?
I'm getting a few errors when I go through the store checkout:

United Parcel Service (Weight: 130.00g)
111057: This measurement system is not valid for the selected country.

Does the info you enter in this module affect the final rates calculated?
Do we need to set up anything in our ups account for this to work?
All I did was sign up, request an api and entered the info in the module.

Pretty confusing stuff.
