Don't believe Camry needs new water pump and has oil pan leak so early.

Air filter: Toyota OEM $20, oof brand $10, DIY. Just a couple of nuts and clips.  You suppose to change around every 15K miles depending on how dirty is place you drive;

Cabin air filter: Toyota OEM $25, off brand $15, DIY.  Just a single screw to release glove box lid.  I believe you need to change every $20k miles or when you smell someting bad;

Battery terminals: DYI by cleaning with bakin soda solution and putting some battery grease and washes;

Coolant: $15.  DIY.  You don't have to flush.  Just drain and refill.

Transmission and power steering: You usually do not need them for now.  Transmission fluid is recommended around 45K miles but check and you may not need to flush it until 90K miles.  I don't think you need power steering fluid either.
