Anyone do a courier route or something similar with their Yaris?

[40mpg]

I do a courier route in my 09 Yaris, 480 miles a day 6 days a week. I've got a few questions:
What brakes are you guys using?
How many miles are you getting out of your clutch?
I have Firestone FR710 tires and LOVE them, is there anything better?
Is the K&N drop in worth it?

My car currently has 178k on it, clutch is still strong, but I do get a little bit of shake from the brakes on high speed light braking. My boss(whose had literally 10 different Yaris') says buy the most expensive brakes you can as the Yaris are prone to go through them, or at least how we drive them. What brands do you guys suggest? He has EBC now.


Thanks in advance!
