After a closer look, I figured out the line weight question. Even ran a test print and all is well. This is what worked for me,
1. Select the viewport in paperspace.
2. Select the lines you want to add weight to.
3. Click "Properties"
4. Click "Lineweights" and change to whatever thickness works.
That's pretty straight forward, but it does change the lineweights in model space, as mentioned above.
