If you have a P0401 code from a CEL, the first thing is to check the EGR vacuum modulator. It is a little well usually next to the EGR. Pop the cap off and dust the little sponge inside. Sometimes this gets stuffed up with carbon particles and causes recirculation problems. You should clean the tubes hooked to it while you are there. Reset the code and see if the light comes back.
Replacing the EGR is not a tidy job. It is an expensive part to replace and you will disconnect the three hoses and dismantle it from engine by two nuts. Save it for the later if the previous trick fails to work.

P1410 EGR Valve Position Sensor Circuit Malfunction
You may have to replace the sensor. If you get a chilton manual at an autoparts store, it will show you how to test the sensor with some test values in the book. The book should run about $20

Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).
Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.
Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.
Fourth, make sure the radiator (and associated hoses) aren't blocked.
If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.
However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.
If all above components test ok, then it's possible your water pump may not be pumping enough volume.

Testimonial: "I appreciate your help...Maybe I should just relace the water pump, that would be the last thing that I would need to replace."
Hi, my first recommendation would be to take the plugs out and visually inspect each one and check to make sure they are properly gapped, if they look fouled at all i would replace them without hesitation. try throwing a set of NGK plugs in the car to fix the misfires. other than that you may want to look at the wires. good luck joe
