Need some help here trying to wire up a 3 way switch. First off how do you know which one is the line switch and which one is the load switch? 
In the first picture the red wire (traveler) goes into the bottom of the switch, but in the bottom picture it goes into the top. Any help would be appreciated.
You need to map the circuit in order to know exactly which is which. Since it sounds like you don’t know how to do that, if you don’t want to bring an electrician right away, an alternative if you live near a home depot is to take one of their free classes on how to install a switch.
The class won’t cover networked switches, which are wired a little differently, but you’ll learn how to use the tools and Map the circuits. And since the GE zwave switches are sold at most Home Depot’s, often instructor can get you some advice on those as well. 
We should also note that most wire colors are not mandated by law in the US, and people can and do use Colors in different ways, often just depending on what was the last roll of wire in the box at the end of the day. So you can never go just by color, you need to map the circuits.
line and load aren’t switch types, the denote the romex going into the boxes. Go here and see if you can figure out 3-way circuit type you have based on the romex going into the two switch boxes
When i called it a Line or a Load switch, I was just following the naming in the Jasco Instructions. I figured it out anyway. Thanks
