Question 2-
I bought ramps even though I have a jack and jack stands because I still haven't figured out where the jack stands are supposed to go once you have the car up. Now to drain the most oil out of the car, should I do the oil change on a very slight decline, so that the car is closer to being level when it's on the ramps?

There are jacking points under the car. I usually jack the car up at the rear tire jack point till the front end (on one side of the car) is high enough to get the jack stand under..... there are better ways to do it but I stick to the jack points cause they are there for a reason. If you drain the oil from the plug let the oil drain for a little while then jack the driver side of the car a little higher so you can get all the oil out. You can also use the ramps but to get all the oil out you will have to jack up the driver side a little higher. Hope this helps!
