You need to copy the entire itunes files from your original pc and upload it to the 2nd pc, then sync.

What Chris said. Alternatively, enable Home Sharing in iTunes and it will automatically keep the libraries in sync.

The computers are 500 miles apart so this really isn't possible. I have all on my iPhone, but when I sync it doesn't update the new computer.

Its enabled on the new computer so when I get to the other one in a couple days I'll make sure it is there also.

The iPhone is not a data transfer device; it will sync with only one computer at a time, and changing computers will erase any content from the original computer and replace it with content from the new computer.
To sync two iTunes libraries (assuming they have content purchased with the same Apple ID) the easiest way is by syncing them both with iCloud. If the content comes from other sources you can sync it with iTunes Match.
Other, more complicated ways include cloud-based file storage services such as DropBox or Box.com.
