60k service for an '06?

Hi, I may be posting in the wrong forum, but I recently bought an 06 Titan with some 57k miles, and an unknown service history. The truck runs fine, and looks good, but for the hood's clear coat. I changed the oil/filter and did some other minor repairs, but have read about the need for 'major' sevice. I do not have a mechanic I can trust - including a local dealer, who begrudgingly did the recall service, but ignored my request to check and reset the TPMS. The tire pressures I'd adjusted before taking it in, but the light stays on - some have told me that each sensor needs a new battery/replacement before resetting the warning light.

Having found a maintenance service manual on line: https://www.nissanusa.com/pdf/techpubs/2006/2006_N_SMG.pdf
I'm thinking of having the 60k mile fluid service. Not including the Costco coupon, another nearby dealer quoted a labor charge for replacing the following fluids:
$250-300 AT (do I have a CVT?)
$130 brake fluid
$200 differential oil
$130 coolant flush

I've done similar work on my other older cars, but am wondering if the price is fair and what work needs to be done. I do not have a service manual.

Enjoy
