sounds like a good car
oil: not quite sure... my 06 doesnt use a drop of oil and i use full synthetic 5w30 but i kno the gen 6 takes 5w20 or 0w20.... not sure if thats why they sometimes burn oil or not
coolant: i wouldnt touch til about 100k..... i would watch out for water pump failure though, that is common on the 2azfe; make sure u stick with toyota pink coolant
trans: its really up to u, people do it at different intervals anywhere from every 30k to never......; make sure toyota WS fluid is used
air filter/cabin filter: again really up to you, toyota is good but more expensive..... aftermarket purolator is fine and if u want something a little better i would go with beck/arnley or denso
battery: i would have it tested just to be safe (advance does it for free)..... honestly brand doesnt make much of a difference the main thing your looking for is warranty and cold cranking amps..... toyota's are easy on thier batteries so they will last a few years between changes
spark plugs: i would highly recommend NGK irridium plugs..... denso is good too.... originals are good to over 100k but it never hurts to change them before hand
brakes: get them checked just to be safe but again, toyota's are easy on thier brakes when good stuf is used.... if pads need replacement i HIGHLY recommend akebono
wipers: just check them for wear and drive it in the rain and see if you can see lol..... if replacement is needed i would highly recommend bosch icon or valeo 900 series
good luck with the new ride!
