I have to assume you have a 3.5 liter engine......the first diagram is all you need to locate it : http://www.justanswer.com/chevy/5xwod-change-oil-filter-housing-oring-gasket-2006-3-5-litre.html
Is the check engine light on? Do you have good fuel pressure?

Call a Toyota dealer and have vin# ready. They will tell you if there are any.
Calipers don't usually get repaired, they replace them. For cost, try the estimator at the top of the page.
Yes, you have to do most of it by feel and laying on the engine, but in reality, it's only four bolts. Proper tools are key here. Do not go in with a handful of adjustable wrenches and think you will get it. Make sure you have 1/4" drive swivel sockets (8mm and 10mm), a handful of extensions, and a comfortable something to lay on. You will be on your belly for a whole hour. One tip that I did not see posted is to remove ALL air hoses that are in the way. I did not do this until I was half done and it would have saved a lot of time. They just pull apart at the joints. Hardest part for me was scraping old gasket off. 1. Remove all air hoses that will be in the way. 2. Remove 2 bolts holding exhaust tube to EGR (use 8mm box end wrench on forward bolt and 8mm swivel socket with about 2" extentions on rear bolt. 3. Pull tube from EGR and intake. Don't worry about gasket. My EGR (from NAPA) came with both gaskets. 4. Remove 2 bolts securing EGR. (10mm swivel with enough extentions) 5. Remove EGR and clean ALL gasket material from surface. Keep in mind this is a metal gasket. 6. Pre-assemble new EGR, hose, and gaskets. Keep hose bolts loose enough for hose to move freely. Thread in EGR bolts far enough to just hold gasket in place. 7. Carefully put EGR in place while lining hose up with intake port. 8. Tighten EGR bolts first, then hose bolts. 9. Hook all air hoses up that were removed. 10. Reset check-engine light. 11. Have a beer and tend to all cuts and scratches on your forearms. Hope this helps. Found this for you......too lazy to type all that myself....LOL! It is a tight, blind job done by feel and maybe with a mirror assist. You will be laying on top of the engine to do this.
