I have a pair of 16'' Channelocks that I eventually discovered worked better on oil filters than many things meant for the purpose. They work about like the pliers type ones, except they are heavy duty enough to use for a 1000 other things. If I was buying something specifically for oil filters, I would pick up one of the socket caps for them. they are cheap, and if your next car takes a different size, you can just buy another. Most people need a wrench to remove filters. Some people need a wrench to tighten one. READ the directions on the filter. Keep filling the filter with oil and letting it set until the level stays where you can instal it with spilling too much oil. That varies with how the filter is mounted. Usually I can't do that without getting plenty of oil on the gasket as the directions say. Once the gasket contacts the base, turn it up to a full turn, and no more. It should not leak but come off with reasonable efforts if you oil the gasket and do not over tighten it.
Before buying ramps I would checks 2 things. Depending on how you, and your car are built, you may be able to change the oil and filter without raising the car. If you need ramps, make sure your car will fit the ramps you buy. The bumper on my newer cars will not clear the top of my older ramps. I made some sturdy wooden ones that do fit.
