Dunno how closely matched the area is in your 3rd Gen with my 2nd, but here's what I do and you can get the supplies at local autozone so no need to wait for the mail... .
I use an old strap wrench that works awesome. It's the kind with a 2-3" wide nylon strap attached to a 5" square pipe that accepts a 1/2" driver at the end. The more worn out the better; it seems the new one's are a bit slippery and stiff until broken in (mine used to live in the bilge of a big commuter boat with giant CAT diesels so it's broken in nicely)
Anyway, just soak the new one in warm water before use and strap shouldn't slip.
Here goes:
Tools: StrapWrench, 1/2" driver(fixed is better than ratcheted), 1 foot extension, 1-Gallon ZipLoc Freezer bag, old towel, screwdriver, sharpie felt pen. Small step ladder. Rubber strap wrench(like the kind they used to sell on TV)
Unscrew clamps that secure rubber air-intake duct and remove it. Carefull around the turbo intake (cover it with towel/rag. Cover altenator area with towel too; I've heard of folks shorting out somtehing around there, so no need for that. Slip that strap up under end of filter and slide it all the way up to edge (not that hard, but the crux of this procedure). Snug up the strapWrench and connect the extension and driver. Turn (in correct direction; clockwise I think). Filter should loosen up without much fuss. Don't unscrew all the way.
Once it's loosened, remove strap wrench stuff. Slide Freezer bag underneath filter (another crux for those of us with limited elbows and large hands) and spin off filter. I find that I have to walk top edges of baggie around to keep it above filter. By holding onto top edges, you can unscrew, lower, and maneuver the filter around and up through all the obstacles. Just make sure its a Freezer Bag or similar strength! Wipe the area where O/F gasket seals with to remove any foreign objects or leftover rubber. Fill up new O/F with oil and smear a little on gasket. . Replace gently. After snugging down hand tight, I use a rubber style strap wrench to snug the O/F a bit more, but not gorilla tight b/c my hands can't get it tight enough. Make sure to keep the rubber strap around the top edge so it won't dent the O/F. After all this, I mark a spot on the O/F where I have a mark on alluminum base where it attaches. Then I check after few hours on the truck to make sure it's not slipping off. I also write date & mileage on filter in case I forget when it was last changed. Replace rubber air-intake housing and that's it. Of course, I'm assuming you already know how to drain & fill oil.
Lots words but I have no problem replacing my O/F and although I'm sure there are better ways to do it, I' have no reason to change.
Hope this helps...
