Welcome. Your angles don't look too bad. Your lift is a quality one and consists of a drop bracket which keeps the angles near stock. When one needs to be concerned is on coil over style lifts that are cranked too high, stacking lifts Maui style, or anything around a 3" with no diff drop. You'll hear others thoughts on this, but this seems to be my experience.
I used to have a Tacoma with a 6" Fabtech that ran about 100,000 miles before anything started going out. I'd make sure the lift was installed correctly and that Bubba didn't have a handful of parts left over when it was done. Other than that, enjoy.
