ok here it is (I'm extremely bored out of my mind and decided to take the photos before I forgot), I took the pic of the radiator drain from the front of the car and the one of the engine block drain plug from the driver side of the car, i labled the spark plugs so you would remember its on the same side.
if you need any more help, just ask. Also, i forgot to mention that if you run less radiator fluid to water ratio (hence more water) you get more cooling, water transfers heat more efficiently, if you live in a tropical enviorment like me in Hawaii (where the temp never drops below 70 degrees F.), you can run about 17-25% radiator fluid to water. When I did, my temp went down from 200 degrees to about 180 (i also ducted the air in to my radiator as well as took out my A/C condensor which also helpped alot with the cooling). when my brother did his, he dropped to about 180-185 from 200 as well and he is bone stock (no mods done to the front of car and he is running A/C). If you do live in freezing weather, you can run what ever you usually run.
Good luck
P.S. Are you planning to run the green radiator fluid or the red/orange havioline stuff? personnaly I say stick with the green stuff, I have read bad stuff about the red/orange havioline stuff but its your car so you gotta decide on what you want to do with it, some have sworn by it.

biggest and most helpful hint I've ever received:
when refilling the system (both for the flush cycle and the final refill cycle), remove the coolant host to the throttle body. This will allow air to escape from the system while you pour in the water. Otherwise, you'll spend an hour or more burping the system. You should be able to fit just over 8 quarts in one shot if you go about it this way. Once fluid comes out of the TB hose, put it all back together, drive around the block with the heater on nutil you feel heat (which means the thermostat has opened), let it cool down for a bit and top off at the filler neck.
and as far as orange vs green - I switched to the orange, but, if I had to do it again, I'd stay with the green. the advantage to green is that it has more silicate, which is like a lubricant, so it flows more easily. The advantage to the orange is that it is thinner and supposedly sheds heat faster & leaves less deposits (it has no silicate). However, switching may have adverse effects on your seals, so just keep it the way it is.
oh, and make extra sure that you put the coolant hose back on the TB before you drive around.
