The port on the larger of the 2 A/C lines coming out of the compressor is the low side.

On top of the engine, under a little black screw-on cap. In the attached link/image, you can see where it is. http://img40.imageshack.us/img40/9510/img2160h.jpg http://img40.imageshack.us/img40/9510/img2160h.jpg

Did you hear a loud grumbly noise before this happened? That would indicate a fluid leak from the power steering. Check the fluid first. Top it off to proper level and try again. Check for goopy and oily areas under the reservoir and around the hoses to the rack - that would indicate there's a leak and probably suggest where it is.

Ok, trailer lights are basically separate circuits from the regular stop lights and same with the center brake light. There is a brake light fuse located in the fusebox next to the battery in the engine compartment. Use a 12v test light to see if it becomes hot both sides of the fuse, when the brake is depressed. 12v Test lights can be bought at a auto parts store for less than $15. Do not get a "continuity light" as these are different. A test light, lights when you touch a terminal and voltage is present using the alligator clip attached to a good ground Notice that the center stop light does not go through this fuse in the diagram. I have included a wiring diagram for your vehicle. If you find the brake light fuse blown, and it repeatedly blows, you have a short to ground from the fuse to the brake lights somewhere. First step is to check the brake lights for a short. and work your way back to the fuse.

codes CO222 which is missing RF speed signal.

Probably a intake manifold gasket..

Open the driver door and look at the end of dash...there should be a door you pull off to find the fuse block.

Check the brake light switch on the end of the steering column close to the firewall...

Generally,they will be located under the middle of the dash between the blower and the controls...find a service manual for exact location

Check your dimmer switch first...you may just need to turn the knob and it will come on...

Get a scan tool...a cheap scan tool will allow you to turn that off.

Check the circuit board in the tail light...

Easiest way to tell is look at the connection ports where the charging hose connects. If it has threads on the outside of the connector it's a R-12 system. If the ports have no threads then it is an R143 system.

You don't really need a #. Go online, punch in your vehicle and ask for mirrors. You'll probably find 1000's of people that want to sell them.

Check the intake manifold gasket. If it leaks it will draw air into engine and this air bypasses the mass air flow sensor which will cause a rough idle or running symptom from running too lean. If you change the intake manifold gasket you should probably change the valley pan gasket at the same time. A dealer will change both for less than $500 and you might save some more if you dig around on GM Service website and find a coupon discount (Usually 10%-20%). You might save more at a local shop if you trust them and they do this type of work. Getting to the intake manifold gasket also exposes the valley pan and since you are already there it only takes a little more to change that gasket too. Some GM V-8 engines use a little oil between oil changes and if both gaskets are meticulously changed at the same time it will sometimes fix the oil usage. It did for me on my Tahoe (126k miles).

make sure nothing is lodged under the tracks this is common things get thrown under the seat and stops them in the track

Did you put in the battery the correct way? is any light on the key fob? does it come on if you press a button? If there should be a light and it is not coming on, please check if the battery is in a correct place and if all contacts are clean and shiny.
