I'm just wondering I'm pretty sure that its fine temp and everything works like it should doesn't spike at all just when it starts to overheat

As has been mentioned, a t-stat is cheap enough and easy enough to change if youre overheating. You can also check to see it working on your stove top in a pot of water.
Changing out your water pump is pretty easy and straight forward:
Disconnect battery.
Drain coolant.
Remove fan and shroud.
Loosen pulley, remove belt, pull pulley.
Remove coolant hoses.
Remove accessory brackets from water pump but DONT disconnect them. Move them out of the way.
Remove water pump.
Clean everything up and install new pump.
Put everything back together in opposite order.

If possible, while both the t-stat cover and water pump are off, stick a garden hose in the t-stat hole to flush old coolant/crud out the water pump hole. Flush heater core and radiator also.

1999 Radiator Draincock
Been trying the best thread to ask these questions: 1. My 4.0 (2WD) is plastic..right? 2. Since it's almost impossible to access my side-mounted Draincock..I'll certainly need a metal Radiator if i want to have a Draincock drilled-in (on the bottom, ofcourse)..right?

The pulley is sort of half-way pressed onto the hub...it's not a real press fit, but it's tight. As mentioned, loosen the bolts first, then either pop it off with a prybar behind it (carefully, it's just stamped and it'll bend) or use a puller if you have one short enough. Two prybars would be better. It'll come. You may want to tap the face with a hammer (again, gently) to get it to pop.
