Steve,

1) Yes. The temp gauge and fuel gauge are both controlled by the same 
rectangular box, mounted underneath the steering column. It provides the 
proper voltage to both gauges. Assuming your fuel gauge works and you have 
gas in the tank, if you're getting a reading on the fuel gauge (with the 
ignition on), then it's not that box (cheap and easy to replace). The next 
step is to check the wiring at the temp sensor on the engine. 

2) For a 2000, the temp sensor is located behind the thermostat and 
housing. Just follow the top radiator hose back to the engine. There's a 
spacer block behind the thermostat housing; it has the temp sensor with an 
electrical contact sticking out (hopefully with a wire connected). If you 
ground that wire at the engine (with the ignition on), you should get a 
reading on the temp sender. If not, then you have a short in the wire or a 
problem with the temp gauge. If you do get a reading, then your problem is 
the temp sender at the engine. It's an inexpensive part to replace, but 
often a pain to remove. (BTW, on a 1600, the temp sensor is on the drivers 
side of the engine, just behind the water pump.)

About your voltage reg wires, it does matter what wires go where. Better 
get an answer (I don't have one) before trying to connect anything!
