I have a 2003 camry le v6, I did all maintanances by DIY. I know camry very well, maybe can give you some advices.
1. you brake pads: about time to replace if this is your first time to change, parts $60-70 front or rear in canada (mine first time change pads was at 87K km)
2. air filter is easy to replace, $30 parts+0.5 hr labor. 10mm ranchet or screw driver
3.coolant is easy to change too. there is a tap on the bottom of rad. just drain and refill,$20, never let anybody flush you rad. you can do it next spring or whenever
4.the rest ones I believed they just steal your hard eaned money
5. checking your oil pan, make sure all screws are tied. hopply you know what it means
welcome any question
