I did it myself also in my driveway, took 10 hours since I had friends over and we goofed around alot but W37V pretty much covered everything.

The bottom ones you definitely can't mix up since the plugs are color coded yellow to yellow and green to green if memory serves me right. Just a bit more info on the O2 Sensors to make it easier so you don't mix them up:

Bank 1 - Front Header (Closest to Radiator)
Black Sleeve O2 Sensor Wires Only

Bank 2 - Rear Header (Closest to Firewall)
Grey Sleeve O2 Sensor Wires Only
