I'm trying to replace a single-pole switch with a z-wave switch. I'm new to electrical stuff, I understand a little of the terminology just from reading the black & decker wiring book.
I turned of the circuit at the panel, verified with a voltage tester that it was dead, removed the wall plate and pulled the wires out of the box.

There are 3x cables coming into the box: 1 on bottom and two on top. It looks like:
- all three grounds are twisted together
- all three neutrals are twisted together
- two of the hot cables are twisted together and pigtailed to a switch terminal
- the other hot cable goes to the other switch terminal
I'm not sure why there are three cables since this is just a single switch going to a single light. There is an outlet on the wall below, maybe that has something to do with it?
I'm trying to figure out exactly how I should connect this new switch up. Any advice (geared towards a complete novice) would be much appreciated, and definitely any basic/generic/practical/troubleshooting advice & suggestions would be a great help.
Per bib's advice, I tested the individual lines ... and drew up how it is, and how I think the circuit should be rewired with the new switch:
I have some wall-nuts (push connectors), but no electrical wire ... I'm not sure what to get for wire ...
Wiring it up, hopefully I'm not doing stupid things. First time I've done this, so I probably am.
Edit 3: Wheeeeeee, it works!
