Let's see if I can help:
1. & 4. sound like the same problem. The clutch cable isn't adjusted properly. It needs to be able to move the clutch actuator lever a good inch or so to disengage the clutch and allow the rear wheel to rotate without moving the engine crankshaft.
2. Yes, the twist grip should return to the idle position when released. make sure your throttle cable is routed so there are no sharp bends or kinks and that it is installed correctly in the carb.
3. Soldering the connections is prefered over twisting and tape or wire nuts. Most kits provide you with metal push-together terminals but they are notorious for coming loose. The best and most trouble free method is soldering and using heat shrink tubing over the connections.
Hope these answers get you started but don't hesitate to come back with more questions if you need help. You'll get more responses as the evening progresses.

Dylan,
As long as you put "the brown thing" in right. There is a long slot in one side and a short one in the other side. The long slot goes on the right side if you're setting on the bike looking down. I just looked at your photos. The throttle cable should not bend like yours does when it comes out of the carburetor. It should go straight up and out to the handlebar twist grip. The way you have it now is probably the reason it does not spring return to the idle position. The cable needs to make gentle bends to keep it from binding. Did that help?
How are you doing on the clutch cable adjustment? Still need help there?
Tom

2DOOR is right,I looked at the pics and the throttle cable is bent way to much,the cable should actually be going toward the handlebars not the back of the bike,let the extra length of throttle cable stick out in front of the handlebars....Also your clutch cable is way to tight,loosen the cable screw and let it slide out a bit more,there should be a little slack in the clutch cable....On the wiring from mageto to CDI,blue goes to blue,black to black and white to the kill switch....

P.S nice Trek bike by the way....
