Incredible 4G LTE: Things I need to do after getting s-off

I went through the tutorial found here and was able to unlock the bootloader, get s-off, get CWM installed, and superuser. Here are the questions I am having now. 1. Should I relock the bootloader after getting s-off? Will that prevent me from doing anything? 2. In that tutorial under the facepalm instructions, do I need to do step 7 if I already got s-off using facepalm? 3. How can I remove *** TAMPERED *** from the bootloader?
