I was told that I should remove the underhood insulation pad and the real hood seal to help keep engine compartment temps down .... is this true ?

I don't know why you would want to remove the underhood insulation? that won't have anything to do with the temp of the engine. I read a post about the rear hood seal.....in theory it should work. Let us know if it actually changes anything.

ok the only problem i see with removing the rear seal is water. Since most dakotas with 3.9, 5.2, and 5.9, have distributors my only concern would be with water entering through that opening and then falling on the distributor cap and even better if you had an open element filter on top of your TB then you could quite possibly ingest water through it. Removing the strip would help to reduce some underhood temp and if you have an open element air filter could help it to inhale some colder air but at the cost of possible water ingestion through the intake and posible water contact with the distributor also it will cause your windows to fog up easier too
just my .02 cents

There MUST be something wrong with your fan..if it gets in the red, that is too hot.

I agree with Rascal and Eric...fan or t-stat is not working properly. The underhood insulation is there primarily to protect the paint on the hood from excess engine heat and should have no effect on engine cooling.
I had a problem with my dak right after I bought it: a/c would blow lukewarm at stoplights and the temp guage would go almost into the red. Took 2 days for the dealer to figure out that the a/c fan wasn't plugged in. I'm no brain surgeon, but if something electrical isn't working, the first thing that I'd check would be to see if it was plugged in. But hey, it was under warranty and they gave me a rental car.

Does your Dak have a clutch fan or an electric fan? A stuck t-stat will (usually), cause an engine to heat up immediately and stayed pegged.

Also...I cant seem to get my idle from staying at about 900 RPM ........ the TB and sensors only have about 1000K on it...

I can only help you rule out one sensor (though they're new), and that is the coolant temp sensor. If it were bad, your temp guage would be wrong. Mark a possible defective sample of this off your list.
If it hits that temp at a stand-still, rev your engine. Does the fan sound? If not, it's not the problem. If it does, it's either so incredibly hot it cannot keep up at idle (mildly possible with high humidity and high temps - like over 100F) or there's something else wrong. For reference, I sat at idle for 20 minutes with a 180 thermostat and a/c on and it reached standard 195F temp for the first time ever since new thermostat when I drove off in 98F with oppressive humidity; it engages the fan when I take off after such an idled lunch break in less humidity at 105F temps, but doesn't discernably pass 180. My Sport has no hood insulation and I had the rear weather strip removed, though now I'm thinking about replacing it due to above post!

What is your YEAR and engine? Manual/Auto tranny?
Starting in 2000, the Dakota received a "dual" cooling fan setup. (electric AND a recalibrated fanclutch)
The operation of these two fans work together to keep the heat down. Standard troubleshooting techniques may not apply since the ECU controls some of the functions.
Also keep in mind that the 4.7L V8 Hemi uses a "bypass" cooling system that operates differently than the ol' "thermostat on the top of the engine" design. If you changed the tstat... MAKE SURE that it is the proper type that seals off the bypass passage at high temps.
Otherwise you WILL have overheating problems.
