2000 4.0 TJ coolent leaking-what to check before buying a water pump?

Just got this jeep the other day. Noticed that after driving a few miles I get about a cupor so of coolent on the ground. The coolent comes from the engine so I've ruled out the radiator. I'm guessing it's a water pump.
Questions:
1. Where else should i check before ripping out the water pump.
2. How in the heck do I change a water pump on this truck?
3. Best palce to purchase said water pump.

Thanks

Did you find out were it's leaking from?

If it is the WP just go get a new one @ AZ or discount or any auto parts store. They are very easy to replace with just simple tools.

Or you can go my route and get a high flow WP. ie flowcooler brand. And your replacing the WP also change the thermostat why your at it. It sits behind the WP.

Good advice. If it turns out to be the wp I'll change teh thermostat at teh same time.
