Welcome to another 3vz-fe owner!
Stockholm, Mississippi is a beautiful place too!

(that's a joke)
Don't freak out that a few things may be in the opposite side of your engine bay. Remember north american cars drive on the other side of the road!
The air filter is in the black plastic box, middle of this shot

The box is held together by 4 clips that pop off (normally with a little force, so don't hurt a finger!) To pull it all the way off, you may need to take the rubber hose off. Just be careful. Normally they're split open at this age, and that is very bad.
The oil filter is under the exhaust manifold's heat shield. See the rather larger silver part at the bottom of this picture? Three nuts hold it on, and you wiggle it off. Be careful not to break the o2 sensor. (you'll know it when you see it. It looks like a little plug with a wire comming out of it bolted into the side of what you're taking off) If you want, you can cut the part of the head shield that goes around this sensor off. That makes it a hell of a lot easier to take the heat shield off!

If you dont understand what I'm talking about don't worry. You'll figure out what I mean when you go to change the oil filte really quickly!

Which exposes
Drain the oil from the pan before you take the filter off, and when you do take the filter off, have an old towell (or large worthless rag) wrapped around the filter, because it's going to dump some oil out and make a mess.
If you need any help, feel free to post it in the Camry forum, or contact someone that looks smart, like racergirl.
