Also don't use caps locks it represents shouting in forums and most people do not like it and some won't reply to poorly constructed threads or ones in all caps since it can take awhile to see the questions and such.

As for your questions.....
You will have to check with your local laws about emissions, or post in the regional forum for the Georgia region they will be able to give you a good answer.
The SES light should not come on with the sims in place
The sims go in place of the O2 sensors so you have to put them there.
No matter what you do the header swap will not be legal, it is illegal to alter the placement of the catalytic converters.
High mileage ls1's are common and some hold up and last a very long time some don't. I think as long as regular maintenance is done they can last a very long time.

how do o2 sims work do they actually screw in to the existing 02 sensor bunge.???? or do you just plug that hole, and plug the sims in to the 02 wires and hide them

wow...thats weird. i had 02 sims on my stang and they just plugged in between the 02 sensor and the connection going to the ecu. headers wont be legal. you could get high flow cats and flow nearly as well if not as well as o/r exhaust. it is illegal to replace cats on a car with under 50k on the odo (unless there is a problem). you wont pass emissions without cats. end of story.
