That 5.3 is a super tuff little engine and will take tons of abuse. But it is a little engine with a lot being asked if it. Don't worry about letting her rev.
The trans is another issue. They are not as bulletproof. I would recommend getting fresh fluid in there and installing a cooler and temp gauge.
I'd have to agree on both counts - last year I had to have my Avalanche's 4-spd rebuilt but it's been running fine since. I've given the truck to my son so it no longer has to tow and will probably now continue to run just fine for many more years. :)
