Good news everyone:
I have found this CAB from
meltwater who originally came up with the Facebook tab. The CAB is the provides a detailed settings menu that solves plenty of the problems that people have had with the FB tab. I have tested it on my own Sprint TP2 running on Sprint Lovers ROM, and it works great, and it does uninstall as well. You must first install FB tab as provided in the our thread here by chris 1608, and then while Sense is off, install the CAB for settings menu of FB tab. Softreset and enjoy. For your convenience I am posting the CAB here.
