theres a thread from not too long ago where joe black suggested a new type of oil plug that just has a release valve so you dont need any tools for an oil change you should look it up, looked pretty cool if you dont plan on doing a lot of offroading
as for the oil filter wrench, i saw those and almost got one because my filter was pretty stuck... my secret... my inner computer nerd! i used my mousepad to grip the oil filter, the bottom of old style mouse pads are really grippy, and the cusion gives you that little bit of extra torque, works like a charm (i actually learned this from an ex girlfriend who refused to let me open pickle jars for her, she would go get the mousepad to open them)
